I would claim that, of the existing Haskell code,
StricterLabelledFieldSyntax only rejects unclear ("bad") code, and
requiring it be changed (to be made clearer) is a good thing.
Your proposal would reject /all/ labelled field code, "good" and "bad"
alike. That's a much harder sell, especially without the "future change"
being fleshed out or agreed upon.
All just my opinion, of course! The only way to find out for sure is to
make the proposal and see what happens.
Thanks
Ian
