I am with you on that. Looking back, we good a one-year heads-up for R 3.0.0
breaking. At that one point I could (and probably should) have added such a
provides.
We'll do it next time for a known "big breakage". We should however not go
overboard and add it for R 3.1.0 just because.

Agreed in principle.
Ping me off-list for help with r-cran-mgcv rebuilds. I tend to just stick
things I need into /usr/local/lib/R/ as it is so easy and not all I need
exists as r-cran-* ...
