It'll be out of standard as timerfd is, w/out code savings. Look at the
code and tell me what could be saved. Prolly the ten lines of the timer
callback. Lines that you'll have to drop inside the current posix timer
layer. Better leave standards alone, especially like in this case, when
the savings are not there.
