just to note, i am not disagreeing with you but a small comment to this
patch nonetheless:

imho the current state is rather broken, for http urls it uses the proxy 
but not for https (isos are often hosted on https for now, e.g. debians)
ans since at least one person[0] expected it to use the proxy in any
case, i'd argue that for now this would be ok

yes a more general approach with specific uses/allow/blocklist (however
we want to implement this) would be better, but can still
be done after this
