Hmm, I tried to explain with:

Ensuring that this remains true is very important. From the USER's point
of view, it is one of GDB's important features - remote/cross debugging
just work. From the GDB developers point of view, it is one of the
things that make GDB maintanable. You don't need an s390 to check that
the change to s390-tdep.c is probably correct.
enjoy,
