I mistyped, sorry. Should’ve been “1Writer does not use a UUID in its URL scheme and it works fine.”
I use 1Writer’s URL schemes regularly.

FWIW:
I link to iA Writer from my Jekyll site (generated from an Obsidian Vault) for any internal links that haven’t been created yet:
(separated out line by line for easier reading here)
ia-writer://new
?edit=true
&path=path/in/app/to/newfile/20200901-titletextstring.md
&text=---%0D%0Atitle: Title Text String%0D%0Adate: 2020-09-01%0D%0Atags: %0D%0A---%0D%0A#
This is what iAWriter supports. It works across macOS, iOS and iPadOS. Documented here:
No need for human-unfriendly UUIDs.

I too am getting excited over the potential synergy with DEVONthink. I’ll try to come up with a way to automatically fill in the URL field of every Obsidian note indexed in DT so that I can easily launch a note in Obsidian from within DEVONthink.

Thank you very much for adding this feature! 
This is great. Is there a path forward concerning opening Markdown / vault files on different platforms (e.g. when using 1Writer on iOS?)
How do you mean? You can use the appropriate URL scheme to interact with your notes on each app. (In other words, another hooray for plain text!)
I use NotePlan and Obsidian, and will use URL schemes for both apps depending on what I’m trying to achieve.

When I’m including an obsidian:// link in an Omnifocus item I’d like it to refer to a relevant item on macOS (no problem) and e.g. iOS (problem, because there’s no handler for obsidian:// links). My workaround right now is using some Shortcuts script that will ‘rewrite’ the link to open a 1writer:// link instead

I hear you. In other words, you don’t want to deal with multiple URLs for the same note on iOS vs desktop.
I don’t think we’ll see a solution here until there’s a mobile app available.
(I also highly encourage you to check out the NotePlan 3 beta. )

Dude. How do you collaborate your OB with Devonthink? Does this work well?
Just create a Bookmark in Devonthink with the URL as described in the scheme - it works well such as:

Bookmark, yep. It should be worked like this. Perfect example of establishing connections between these two great apps. Thanks for inspiring me.
Curious question: why do you choose this approach over indexing your vault(s) with DEVONthink?
Good point of discussion
There are two reasons why I choose to use bookmarks rather than indexing my vault(s):
(1) I use Groups in Devonthink to keep multiple sources of information on a given topic - Word files, PDFs, URL links to websites, links to pertinent Google Docs or Google Sheets, Aeon Timeline files, etc etc. All of these can be viewed while in Devonthink by simply right-clicking and choosing “Open With” for files or simply double-clicking for bookmarks. Now that Obsidian has a URL scheme, I can use Obsidian as another type of information to associate with a group and I can open an Obsidian Vault by simply double-clicking the bookmark while inside Devonthink.
If I were to index Obsidian vaults, this would not work. Obsidian files are Markdown files of course, but it is not possible to designate Obsidian as a recognized MacOs app for opening Markdown files. So if I were to use indexing, I would have to open the Obsidian files some other way outside of Devonthink. That would make the workflow slower and much more inconvenient.
(2) In general, I prefer to avoid indexing with Devonthink whenever possible. There are a variety of “gotcha” situations which can occur especially when trying to copy or duplicate or replicate indexed files. I think long-term the data is more secure either (a) Imported into Devonthink [not possible with Obsidian] or (b) Kept with its native app and then bookmarked with the URL scheme.

Thank you for sharing your opinions, those are valid points indeed.
As update/feedback to you: Url scheme works perfectly for me on win10, with Obs 0.8.15 released today.
