Some people take it out for low light operations.
Usually B/W cameras have higher sensetivity that colour and using RGB filter with appropiate software can work well. Bit fiddly, I have seen some low lux colour cameras out there recently. I can get a hold of 0.01 lux cameras, cost a bit though.
EDIT - .003 lux

Interesting...that camera I've shown was touted as 0.0001 lux in sense-up mode. I don't think it would be that difficult to remove the filter carefully with a pair of long-nose pliers.
