AIUI, River was just asking who *could* free space,
not pushing
anybody to do so for useful stuff.
I just wanted to mention that there's a need
for them.
I always wanted to make the rendering dynamic (and
then
never expire the tiles), but it would need a post-processing task in
either renderd or tirex (the latter seems a bit more suited for that
from what I read) for the alpha-channel stuff, and ideally do the
metatiling in the same step.
It should not be to hard to write your own renderer.
You may want to
take a look at
