I simply compile the dev frontend to ignore the scheme version. Allows me
to use a master frontend with a 0.27 "production" backend.

Been doing so for years...

The more correct way to do so IMHO would be to stop having front ends
directly connect to the MySQL database and instead go via the backend. So
that way we don't have to rely on a schema at all.

This been talked about for years, if you want to tackle this that would be
awesome.
