I'm not sure what to do next, any suggestions?
None.
My best guess is if the code at least addresses the global remote_fio_data problem it avoids problems with trying to have multiple targets. The re-org needed for integrating it into remote-sim would have to come much much later (i.e., it probably wouldn't happen).
Corinna, can you please check this into the mainline but with the rename:
gdb/fileio.[hc] -> gdb/remote-fileio.[hc]
commit/use the attached include/gdb/fileio.h.
