I agree.  The user has no reason to be meddling with those (unless
he/she is debugging a debugger, but he/she could still check the values
that are loaded there while they are still in GPS registers).

I think we should consider these debug registers as some piece of
debugger hardware similar to one of those JTAG devices, a kind of
CPU-embeded logic analyzer or something of a sort -- some debugger
device that GDB uses, not as an inferior resource.
