It seems to be unlikely there are systems out there relying on a
boot-time mounted filesystem whose device path (or label) contains a
backslash. Certainly not a great deal of those.
Maybe you care to give us some concrete example. Who knows, there
could be a BSD distribution, that I failed to notice, with a really
bizarre naming convention for the device drivers.

Acute observation, indeed.

Maybe you should leave alone the generic considerations of
circumstance and write some code yourself.
In the past 8 years there have been three different proposals and
concrete implementations. You could add your own. So we would at
least know what you mean with "backwards-compatible way".

Then, why do you write it again?
