   Converting them to breakable items adds 3 grobs per break-point, so it

   has a certain cost. Since these items don't participate much in the

   Yes, I know this is what prompted to convert these to spanners in the
   first place. Of course, changing them back would require benchmarking.

   If the overhead is noticeable, I suspect it could be at least
   alleviated by adding is_live () checks in a bunch of places doing
   expensive processing; that might be some work but it might also benefit
   performance independently from instrument names and system start
   delimiters. But I say this without being good at profiling or improving
