On one hand, this could provide a lot of value as some things are just plain hard to explain using only words. On the other hand, aren't you worried about when someone else comes along and needs to update one of those comments? If they're not aware of this tool, it's either going to be incredibly tedious or simply not going to happen.

As the other commenters put it, i dont think this is a huge issue. I usually use this for architecture level diagrams, and that shouldn't change often/at-all. In-case it does change, doing a new diagram is perfectly in-scope of whoevers working on that.

Add a one line comment stating that it was edited by monodraw.

Looks like Monodraw a mac only BTW. That should be fine if macs are mandatory for all the devs on a project, but it would otherwise create a kinda weird situation.

Since they're text files, you can also say "Please copy to a ASCII diagram editor and update there (e.g. Monodraw, asciiflow, etc.)".
