I think you are waiting for miracles. But whatever.

The key word is *may*, you don't *know*. Why do you insist in
committing this reification fallacy?

This threat is not real, it's theoretical.

But let's suppose you are right, and there are issues, and those don't
get reported in v3.12. That is actually GOOD, if people don't report
issues, it means the issues are not that big, or not even *there*.

And no, we won't be in a spot where whatever we do will break things,
because if the intel backlight driver works correctly, that solution
would work for everyone. And if it doesn't, we should stay with what
works best.

Again, screw the users. We are stuck with broken backlight for several
more months to come. Great.
