I haven't tested on other drivers. (Someone buy me something!)
Are you saying that you don't think this is necessarily in spec either
(like the bad_constant_folding() trick), or just that it may not work
on other drivers?
If it's in spec, I'm not sure I can care too much about proprietary
drivers. Within spec and confirms a piece of functionality in our
driver seem to be the two most important criteria, and maybe not even
in that order.
