Should we strictly use extensions for anything newer? That would have
almost the same effect as using a higher version while making it more clear
what we support.

The question is if versions older than 2.1 can be dropped in order for

Yes yes yes! Or not forget/neglect to code a fallback for something I
*assume* is available on a random user's system. Check for 2.1+ at startup
and so many assumptions are verified. The much smaller number of useful GL
extensions is easier to remember to check.
