We built packages locally and upload them there ("Importing a new
package" section on that page).

This reflects my understanding of the situation as well.

Fully agreed. I've just done it and this time there was no conflict to
resolve whatsoever; I didn't check if the resulting feature/buster
builds on Jenkins yet (but it was broken before anyway). If that's the
main or only blocker for option A (vs. option C), then I volunteer to
do that myself regularly.

Absolutely.

I'm fine with you folks trying this out for a while if you want, e.g.
until we ship a first public beta/RC with security support (once we're
there, I don't think that these lower expectations will fly anymore,
and we'll need to revert to either option A or B).

Fair enough. As you know, I personally think that the drawbacks of
removing this precondition outweigh the advantages, but I won't argue
endlessly about it and I'm happy to see you try your preferred way :)

Right, it's good to keep this in mind!
