Creating additional instances of QOpenGLFunctions for the same context will automatically share the internals behind the scenes so "it's way too much memory and time for each to resolve is functions" should not be the case. Also, functions that are never called are never resolved.

This is great :-) So I guess the internals are also shared between shared contexts?
And does this mean the QOpenGLFunctions_* default constructor will do "the right
thing", assuming there's a current context?

If that's the case, then subclassing is no longer an issue.
