only because of very constrained weight budget (which is constrained by the high price of delivery into space) so you can't just throw in an AC with a radiator. The radiative power scales with the 4th of T, so it is pretty effective in space if you run the hot end of AC hot.

I suppose there were a lot of arguments about usability and various constrains/impossibilities 30+ years ago when cell phones only appeared at $1+/minute and were available only at a very few places. Yet here we are. The cheap access to space will do the same for various tech-in-space (how about unlimited access to space with fineprinted "cap of 1000kg/month" :).
