  Concept wise, I really like it. It seems simple and well-encapsulated.

One thing I found with nvidia drivers is that if we create an original context with robustness attributes enabled, and then use that as a share context for a new context without robustness, it fails to create anything.

It looks like this code would do that.
We probably want to re-use the kwin code for creating contexts so we can ensure matching attributes
