Often I see apt-get update downloads exceeding 100 MiB. That is without a

I think it might be worth quantifying this. Right now, for amd64
proposed pocket Packages.xz files for the following:
This is what I see:

Jammy:
main 253K
universe 75K
Bionic (as an example of a mature release with fewer SRUs in flight):
main 131K
universe 9.7K
There are maybe some extra round trip times to consider, although apt
does do HTTP pipelining so I'm not sure.
I'm not counting sources, since presumably those with bandwidth
constraints would not have them enabled.
It's worth noting that I don't expect these to cache (unlike the release
pocket) since they change regularly.
But these results are much smaller than I was expecting!
When working with a mobile connection this is already problematic. We should
strive to get this number down. Adding proposed is going into the wrong
direction and would only help a tiny fraction of all users.
Everything is a trade-off, of course. If we were adding just one byte
then perhaps you wouldn't object. So, given the above sizes, do you
still hold the same opinion?
