I don't think it's got to do with mmm-mode (it might even predate it).
More likely it was just an arbitrary decision.

I believe hs-minor-mode should not be permanent.  Just like
outline-minor-mode.

PS: Note, that if you remove the permanent-local property from these
variables, then you have to add a change-major-mode-hook to turn off the
minor-mode explicitly (so that it erases the overlays).
