Yeah I really don't understand why this crap needs to be so capable. You can already do all sorts of tricks with net booting, any HTTP stack needs can be deferred to run in the OS. I worked extensively with UEFI in a past job and every implementation I could find had large bugs of some kind. It is fine at booting the system but managing it is a nightmare, and it seems like UEFI prompt is designed to be as obtuse as possible. And I didn't even know it could do HTTP calls!
