Thanks for considering this. I definitely think that with the number of
packages increasing, sooner or later this will be a (more) serious issue.
In some cases it is also hard(er) to work around with detaching and
re-attaching packages.

I think a NOTE would be probably enough, because probably a lot of packages
have these issues.

Also, people would not need to change their package _now_. Only if and when
they submit new versions. But that's CRAN's decision, not mine.
