I agree completely.

The people I know of who routinely need to deal with "morphospecies" fall
into the former category, for the most part. Except, it usually has little
or nothing to do with conservation management, and more to do with large
numbers of morphotypes, for groups that tend to have more than one life
stage, and whose biology is not well understood. It's usually the case that
insufficient information and/or expertise is available to make a confident
judgement as to whether a new species-level name is needed.

So....it seems to me that we are basically in agreement on this point; as
populations with consistent morphological differences that are deemed to be
too small to indicate reproductive isolation (given available information)
are prime fodder for "candidate" species.
