Why do all these kits come with a relay per door?

Is it that the input wires in the harness/ckt aren't big enough? Why not use one relay for the whole ckt?

I can understand a bit if your rolling up 4 windows all at once so you might have to beef up the wiring or separate them, but really one per door?

Sorry just seems to add more crap to fail and more unnecessary work on the install.
