You're right. It solves a problem. So in that case it is an absolute
need to have for end users. However, ANGLE itself should not have a
reason to exist if the drivers where working like they should.

As said before. Vendors should be motivated to fix bugs. Having ANGLE
in place makes fixing bugs a less important priority.
You could even continue this reasoning and say (as a driver vendor):
"Kill OpenGL out of our driver and install ANGLE by default"...
