I believe that the target audience is non-tech end-users. Most
orgnizations already optimized their way of downloading .debs via some
way (e.g. auto-apt-proxy) or another. As you point out, organizations
are easily able to deviate from defaults. They're not our primary target
with defaults.

Laptops of end-user systems are the target, but also developers. When
people gather at a place (conference, hackspace, private meetup, etc.)
downloading of .debs should just work quickly by default. Many such
sites could easily provide a local cache and a number even do. BSPs tend
to have a blackboard with information including the local mirror to use.
Seriously, how many people change their mirror when they go to a BSP? If
we installed auto-apt-proxy by default, much of the local caching would
just work.

The thing we seem to be disagreeing on is what is more important? https
by default or quick and efficient downloads? Some may think that our
CDN can handle the load just fine and the effects of caching are
peanuts. I can attest that those peanuts are 4TB/year (equivalent to 8
days waiting for downloads) for me.

I see that we've given up on a global network of independently-managed
mirrors and that CDNs are way easier at this time. While initially CDNs
had bad reliability issues, those have completely vanished in my
experience. On the other hand, local caching still outperforms CDNs by a
factor of 10 or so. I'd love to make it the default.
