It's certainly fine to provide only *at flavors for any new syscall, IMHO.
The * case is always just a simple degenerate case of *at, and libc can
trivially provide the simpler user API as well using the *at syscall.

But please keep the uniformity that everything taking a descriptor and AT_*
flags is named *at.


Thanks,
