In this specific case, as I understand it, you deliberately want my
driver to be less capable for the next release (and you probably
already managed to do that for 7.11, though I think 7.10 was okay).
What I have so far proposed is:

We need to let *some* shaders through whether they will work or not,
because the current code is deliberately crippling at least one
driver. In order to fix this, some checks should be removed
*temporarily* and reestablished when they're more mature, or another
workaround should be found before the next release is out. One way or
another, no driver should be crippled ever. I know you couldn't care
less about anything except your driver, but there are people who care.
