I like the name \temporary.  Is this of practical use outside of music
functions also?

I like that too.  What about

  \push { Stem.cross-staff = #cross-staff-connect
          Flag.style = #'no-flag }
  $notes
  \pop { Stem.cross-staff
         Flag.style }

[I'm using the `.' operator creatively; no idea whether this works,
and no need to discuss this in case it doesn't :-)]
