The point is that it has been historically possible to push R in different directions even without the blessing of the core team but if its locked down too tightly then we lose that facility and its that loss or potential loss that is worrying. The idea of the package system is that it should be possible to extend R without having to modify the core of R itself.

I don't think so. I think it was changed on us and I think it ought to be changed back.

Some people on this thread seem to be framing this as a quality issue but its nothing of the sort. The specifics cited make it clear that the current handling of Notes is not improving the quality of any package but is potentially causing thousands of package developers needless work on packages that have been working for years. If the Notes are just there to be helpful that is one thing but changing the idea of Notes so that an undefined subset of them are arbitrarily imposed at the whim of the R core group is what is objectionable.
