Databases tend not to make human readable links. Switching systems always causes some upheaval and inconvenience. What you are describing is having to open door yourself rather than having to break out because you are locked-in. Evernote is one of the better database systems for retrieving data - there’s no shortage of them that do lock you in.
[[wiki-links]] are searchable but don’t simply work as links, especially if a name change has removed uniqueness. And the notes are as you wrote them, but Obsidian is a proprietary program too (and I have no problem with that). Many FOSS programs have databases that are hard to work with. And having programs able to work with those links now is no indication they are future proof, even now many markdown programs would require those links to be converted.
Before putting information into a database, I believe it is always worth checking how you will retrieve it if something goes wrong or you want a change. That includes databases I set up myself. There’s always inconvenience and a loss of the functionality that made you want to put it in there in the first place.
