It would be a nice feature to be able to use gef-remote when using gef instead of the traditional target remote used in gdb.attach and maybe target extended-remote used here for instance.

Maybe something like the following could do the trick ?

gef➤  pi
>>> if 'gef' in locals():
...     gdb.execute(f'gef-remote {host} {port}')
... else:
...     gdb.execute(f'target remote {host}:{port}')

This could also be a nice feature to add better support for qemu debugging ? I didn't really tested how it works atm but I guess using the qemu-mode should improve it for gef users.
