I'm not talking about swapping the arch, but about a list of the
methods covered by the arch, and how things like registers, addresses,
and chunks of memory get from the debuggee via gdbarch to GDB.  This
path includes many translation layers which, at least for me, are the
biggest stumbling block when I'm trying to understand how things work
in a certain port, and where to look for possible reasons of some
snafu.

I agree; but in this case even the theory is not documented.
