Well, this is even more global /in general/;) It happens in various libs that are
enhanced, I recall doing a few commits like this in the past.
Ideally, these R might be removed when sover is bumped, making particular symbol
irrevelant as lib would be upgraded anyway.

There is no efficient mechanism to track such dependencies (->dependency
hell) unless one does 'upgrade *' and evades this problem (or something
else just triggers appropriate update).

Only by creating (manually) a database with such 'enhancements'. Every
package that gets rebuild in environment having listed libraries should
automatically get specified R.

But I think it's not worth it - any case we spot (they are really rare)
have big chances to be already late and some packages will alredy be
rebuilded.
