With the release of OpenCL 2.0 there is a feedback window of 6 months.
It would be a good idea to have a similar thing for OpenGL. (For every API, with variable feedback windows depending on needs. )
Having a 6 month feedback window after release of new OpenGL draft specification.
Where there can be public review in how to improve things.
This could improve specifications a lot with more eyeballs bugs easier found and stuff.
Also the working group can more easily get information about the new features use and what is wanted and what is not.
