Look at the sanitizer libraries, which insert runtime checks for
integer overflow - having less overhead for these would definitely
be a plus.

Not valuing something just means no one is spending a lot of time/effort
on it.  Decimal math is not valued--but you can still do it, it just
has no special instructions on most architectures to make it fast/easy.
And as I've pointed out, trapping on integer overflow is clearly not
valued--on x86, where INTO exists, GCC and Clang do not use it.
