FWIW, my take is that treating consecutive special-use labels as a single label
only to resume minimisation at some subsequent non-special-use label sounds too
complex to me.  Intermediate special-use labels are just as likely to be ENTs
and to not be privacy-relevant zone cuts even when some labels below are not
special-use.

So whether it is MAY or SHOULD, my sense is that if an implementation chooses
to implement the proposed strategy it should just make the final query at
that point.
