Yes, I think so, although we deferred discussion of next steps.

To restate in brief: I think it would be appropriate to warn that in cases where  (specification for) the subtype allows for interpretation of any particular identifier(s) in a way that conflicts with that mandated for the base, generic processors will produce erroneous results. The consequences in such situations might include: (1) generic processors become impractical for such types (2) users are inconvenienced by links that do not resolve as intended (3) systems crash or serious errors result from the wrong data being processed.

I think that your note went to Tony and apps-discuss so I imagine that he/they will take it into consideration for his document; it didn't seem to be a comment on the suggestions that we made to Ned for incorporation into the media type registration draft, which is what the resolution was about, but correct me if I'm wrong.

Your comments also seem like exactly the kind of guidance that we'd want to put into a more discursive document about best practices around media type registrations, which is what I was suggesting as a next step from the TAG in this work.
