Yes, please.  You'll need to touch the syscall tables anyway to refer to
some new name, so it really isn't that much more work.

Why would that create further complexity?  IFF those calls need compat
work other than the time structures you will need additional variants of
them anyway.  If the only compat handling is the time structures they
will stay the same independent of the name.
