It doesn't feel OK to me.
The schema would be there even w/o installing the extension
What if another extension wants to do the same?

I'm open to other ideas but JSON schema is not dynamic. Since we have auto install - if a user followed the schema, chose a host at runtime the extension would get installed and all would work. Perhaps this is the way for now for 1st party extensions till we figure out a better way to support this in the future.

My recommendation is to avoid adding anything to azure.yaml that is only understood by some extension.
Keep azure.yaml's schema clean and easy - it's overcomplicated enough already with azd's conditionals 🤓
Avoid to user azd as a midle-man between some extension and the user.
When it comes to extensions, it is hard for me to see the benefit(s) of using azure.yaml for something that is not only opt-in (extending azd functionality).
