Sometimes, this would be very helpful, yes (see attached image from
the last scene of 'Wozzeck'). I guess a possible work-around would be
to (ab)use `DynamicTextSpanner` for that.

What do you mean with 'dedicated grobs'?

I'm working on documentation for all grobs, and I also add cross
references from one grob to similar grobs (if it makes sense). While
doing that I noticed that `TextSpanner` has no auxiliary grob for
aligning.
