Yes. I'm planning to ignore most of bikeshed and take only serious
answers into consideration. Otherwise, we will be stuck with CVS.

It may be difficult to convert it properly, especially considering
the splitting of ebuild+Manifest commit. Then we need to somehow check
if it was converted properly. I don't even want to waste my time on
this. IMO the history doesn't have such a great value.

The same way he currently does :).

As far as I'm concerned, user can use the user git tree to get proper
signatures or any other method that has proper signing support already.

If someone wants proper GPG support in rsync, he can work on that.
