Like with "frame_id", it would mean adding some sort of "special" field.
That way the MIPS could record that its debugging "o64" but with
variation #28: sizeof(long) == 8, FPU :-/

It would also make architecture creation more robust vis:

- fill in "gdbarch_info"
Setting osabi et.al. based on the bfd et.al.

- create the architecture from "gdbarch_info"
but with _no_ bfd.

harder to get right, but probably more correct.

Adding to wish list ...
