I'd hate to have yet _another_ set of translation functions, and
another chance of people just getting it wrong either in user space or
the kernel.

So no. Let's not make another set of flags that has no sane way to
have type-safety to avoid more confusion.

The new flags that _only_ work with openat2() might be named with a
prefix/suffix to mark that, but I'm not sure it's a huge deal.
