Better/worse is not sufficient in itself to justify annoying the user.
So the "why" was really saying "why is it a big enough deal"?

Package installation should indeed work even without those
certificate chains. Either by accepting the "unverified" certificates,
or by falling back to HTTP.

We already have a fallback to HTTP. I think it's sufficient.
