That's a good question (assuming I understand it, it's a bit hard to
parse as written).  I don't know MIG or GNU Hurd.
This stuff is pretty straightforward though, there's no magic.
The answer depends on what GDB uses MIG for.

If GDB on Hurd uses MIG like GDB on Linux uses ptrace,
then that would explain it (again, assuming I understand the question).
But someone who knows Hurd and MIG will need to step up
and provide a real answer.
