Things are easy to implement and maintain when you don't intend to do
the work yourself.

It is not easy to test for every possible brokenness of any compiler or
assembler people come up with on this planet.  It is not easy to
maintain it.

We have long list of useful GMP improvements; I will spend my time on
those.
