That doesn't mean that we should just ignore efficiency. Smaller downloads means less bandwidth required on apple's side as well.

This also ignores that not everyone has stellar connection speeds, and that some people -do- have bandwidth caps (also, let's ignore that people are often mobile). Developers really need to stop making assumptions about people's hardware or internet speeds... and just do their jobs and make efficient designs. Maybe one day everyone will have super beefy machines on fiber optic networks with 10gb nics, but that's not the reality as of now.

If a patch needs to be 2gb, then so be it. But if it could be 100mb, then that's certainly better and something to strive for.
