When will the API be stable?

We've been developing around the D-ID API for some time now and are about to push our latest launch using D-ID.

The list of avatars seems to change all the time with names being dropped breaking our app. I just updated last week and now two of the names have dissappeared - matt and rian this time.

These are breaking changes but your docs say the API is stable. Please can the names be kept or aliased or provide deprecation notice or something so we know when to update our app.
