The main usage for this (as you've said) is for using botstat (as an api) without having to use cilent bots or bot providers as a medium.
As you know, it would allow for various desktop applications to be created to push live (hopefully) updates to the chat.
I'm not really sure what else (besides this) which could be changed about botstat.
Right now, I was and am more concerned about usability of the already defined features, which seemed to do what we would typically expect.
After that, I hope people will have suggestions on various features to add/change for it.
Maybe things like:
Enabling/disabling powers (not super useful, but in specific scenarios, maybe)
Sending messages (sounds kinda yikes)
idk?
There really isn't more to do with it than name/status/avatar/home changes as of now that seems super useful to me.
