Making tests slower is definitely not an option, they are already too slow,
we actually have spent code sprints (Vienna, 3 days) and several personal
hours
to make them faster in face of the growing system and growing number
of modules. On my machine GS il building in 12-13 minutes, without all
that effort we'd be around 20-30 minutes by now.

Sometimes they are, other times not, it's all over the place.

Indeed, it would require two cycles, one to generate the list of CRS, one to
actually produce the caps document.
Unless the list is gathered once and then cached and maintained up to date
using catalog listeners.
