  Not sure if flaming is needed, but I sure never suggested adding
conditional compilation.

  I really can't follow you here, but since you replied after pushing
there is not much point in further discussion. I have said my opinion
and that I do not think there is a no complexity concern in this case.

  I would have just additionally added timeline support like in the
tiny patch I sent.

Anyway thanks for adding timeline and caring about deprecation,
