I though about it, but there are complications:

  * openat2 as generic ABI with its extendable open_how is not a good fit:
    it would require additional versions each time we extend it.

  * We will need to add a fallback for older kernels and Hurd; and I *really*
    do not want to pull the gnulib implementation. Mainly because kernel
    fallback has bitten us in the past and it is a pain to maintain.

There is also the question of each openat2 flag would be really a gain
for this interface.
