What is the most sensible ecmascript build target for a plugin?

I’m working on the scrybble plugin, and I currently have my ES build target set to ES2021, but I’m not sure if that’s the best target.

Obsidian is a managed electron platform, and I’m just not too sure what API version for Obsidian I should target in general, or what kinds of usage statistics there are for different versions.

Is there any at all?

I saw that there’s a usage statistics overview here: Obsidian ecosystem statistics - Obsidian Hub - Obsidian Publish

But it’s way out-of-date, the version distribution is not public I assume? Can this maybe be updated so I know what Obsidian api version and what ES build target I can best use?

We don’t have any usage statistics, only download statistics.
There are people that run old installer versions, so ES2021 is a sensible target.
The API version to target depends on what functions you are using in your plugin and when they where added.
