It does not work reliably with \relative, and the total community
interest to get this fixed amounts to an investment of €25 and no work.

The effort for a reasonably comprehensive solution modeled after the
approach in the presented code sketch would be about 10 times that and
require only a moderate level of skills.  It is just boring and ugly
grindwork nobody can be interested in.

So you should be careful about relying on q in scores that pass music
through music variables or music functions before applying \relative.
