I won't forget why I, and many others, gave up Evernote. It did too much, not too little.
I was reading the plug-in development documentation [0] this morning and the ways in which you can extend Obsidian feels relatively limited. I hope they’ll add more things to hook into.

But I do understand why you came up with that thinking, can't denied that a lot of us did fall into that pitfall of overcomplicating stuff.
Not sure whether this is true. Evernote did much, but on the wrongs parts, in the wrong ways, and then abounded them often in poor state. So in fact they did not enough on the important parts. They barely added the things people demanded, instead added features barely anyone asked for, or rewrote the clients for third or fourth time.
Obsidian on the other side has a sleak core, and everything else is in extensions. Even the core-app itself comes with most parts in extensions. While also allowing the users themselves to add extensions for their demand. This is significant more healthy than whatever evernote did.
Obsidian doesn't seem to be going down that road. Using another provider to store the notes (Dropbox, S3, Blob, self-hosted disk space, etc.) takes care of issues #1 and #2. Making this an optional plugin answer #3.
Obsidian devs have shown repeatedly that they understand why Obsidian is successful - just look at how they released this. No canvas-specific core software changes, just a new plugin that can be disabled.
