How so? It seems to me to be a much simpler problem, instead. It
means that gdbserver needes target_signal_to_host and friends, which is
much easier. If, that is, we change documentation and gdbserver rather than
remote.c.

In fact I'll submit a patch for this later today. Would you like me to
separate the code out of target.c and share it between gdb and
gdbserver, or just duplicate it? It sounds to me that we want to
separate gdbserver further, along better-defined boundaries, so
duplicating it and documenting it would be the way to go.
