A more systematic way would be to have R 4.1.0-2 provide r-graphics-api_14 and
only upload packages providing graphics devices that have a respective
dependency from now on. But I don't know if it's worth the trouble.

At this point I don't really see what we can do other than spreading the word
so the backports users can quickly address the problem by reinstalling the
affected packages.
