What I would advocate would be to make an announcement that in <pick
your grace period> Portfiles will be updated globally to use 1.8.0 key words
that are incompatible with 1.7.1 and that users need to update to 1.8.0
before then to avoid problems.

This is much more user friendly than just doing it and let them find out
on their own (IMHO of course).
