I havn´t tested yet, if the opacity-informations and the assigned grayscale ICC-profile are used in Acrobat, but I would expect that it should work.
Adobe is very active to promote PDF as an ISO standard and also the ICC-specs are now an ISO standard. So it would make a lot of sense to describe the Adobe model for spotcolor opacity and gradation both in the ISO-standards for PDF and ICC-profiles.

It may make a lot of sense, but I'd be rather surprised if this were to happen, since such an algorithm is likely to be proprietary "secret sauce". (This is from the perspective of having created such an algorithm for the Colorbus RIP :-)
