This topic comes up all the time.

It's doable, and in fact, I've been keeping that in mind over
the months, in the direction the non-stop and multi-process
gdbserver support changes have taken.

But, as you guessed, it would take a lot more effort.

I believe that at some point this will end up happening, and it
will be GDBserver's side that will prevail.  It used to be that
native gdb was much more featureful than gdbserver, but the balance
is now starting to tip to the other direction.
