The work is proportional to the number of patches in master to backport
and approximately proportional to the amount of conflicts in the oldest branch

OTOH adding 5 more release branches between existing ones doesnt make a big
difference, because if the patch conflicts nowhere theres nothing extra to do
and if it does conflict in one branch whatever needs to be done i do once
not twice if a 2nd branch has the same reason for a conflict.

fewer branches would just reduce the work on the tarball making and testing side.

So while marking releases "LTS" is not a bad idea. It wouldnt reduce the backporting
work by a noticable amount i think
