I think we differ on what is meant by "supported".  I mean "is
guaranteed by the standard".  I think you mean "works on all known
implementations and most likely future implementations".

I'm happy to use code that is formally undefined but works in practise,
but in this case I don't think the gain is worth it (but that is a
personal judgement call).
