I wonder what causes this, it sounds very odd to me.

To be honest I've always hated the fact that _keeplights exists, because it means that the map is not properly decompileable by default, and even more importantly the q3map2 lights can't be loaded by
DarkPlaces engine if they're missing (it can render them in realtime lighting mode - although I haven't put much effort into making them the correct size/color/etc because most bsp files don't even
have them due to lack of _keeplights).

q3map2 does not even produce these, and quake3 does not render them, I think openquake is the only project that cares about them at all.

More importantly they are directly associated with light sources and thus there is no reason to recover them from the bsp file.
