Free up edicts on desperate maps (i.e. c5m4_quarter) about l4d2-community-update HOT 2 OPEN

I think the point_template and logic entities, and the entities they control (used for the random bombing run/plane effects) could be optimized on this map, I suspect these are contributing to the high entity count.
Just an example of the scale of the bombing run effects, there are 141 env_airstrike_indoors entities on the map.

relay_survival_delete actually optimizes a lot of these things, I think the entities it targets would be a good place to start.
The entity count in survival mode a lot lower due to this, they likely had crashes from the extra survival entities:
Total 1293 entities (0 empty, 1113 edicts)

Personally, I would like to avoid "deleting" brushes from the map where possible, even if they appear to be useless, especially for ladders since they can still be useful when not in use in vanilla or cloning, mods, etc. Brush entities are rarely going to be contributing to the entity limit enough to matter, and could impact gameplay when removed.

Very interesting about Survival and that sounds great. And yeah, we definitely won't delete any ladders, there's even some outside of the map on c5m4. I also tend to enjoy the hidden func_breakable as an easter egg, anyway -- they're near that traffic cone Valve had erroneously solid for all these years, as if that corner of the map was finalized late.
