Lol, so it turns out that F-Droid was a pioneer and innovator, years
ahead of Google ;-)
Looks like a play to give Google more info on releases, since all
releases must go through them. It would also encourage developers to
use Google as the gatekeeper for app releases. I guess this could also
be some kind key backup.
Anyone see anything about their motivations for doing this? I wonder
how much data they have on signing keys getting stolen and abused.
