No since it's unfortunately way too late up upload new upstream
versions for bookworm.

Same here, I noticed the updated libnest2d package is only required
for the 5.0 packages, but it doesn't break the 4.13 packages either,
so I'll just leave everything like it is now. (i.e. no unblock
request)

I was looking at packaging trimesh, but it required too many extra
steps: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=950920
