The way most people use draw.io is using cloud storage integration like Google drive, hence versioning is not possible. So far I never seen people put the draw.io produced file to Git. I'm using PlantUML in some of my projects, it solved the versioning issue. However it's lacking of lots of draw.io or even inkscape editor capability.

There's a plugin for VSCode that brings draw.io editor for local .drawio files. IMO it's the best of both worlds: nice editor and git version control.

Also this plugin works fine in github.dev so it's like a better version of draw.io official site.

I do. What I like the most is the ability to include the diagram source into PNG metadata. The viewers don't need any renderer, yet it can be readily edited.
