I have no interest touching tons of architectures where the maintainers
are much better of looking at those lowlevel bits.  See the case where
Roland tried to do ARM but still hasn't gotten any feedback as a
negative example.

The cleanups aren't there for cleanup purposes, but to actually allow
the utrace-based ptrace being used unconditionally.  There is really
no point in merging a second conditional ptrace implementation that
has to be maintained while we add another one that doesn't add a single
new feature.
