I'm not sure we need to keep history from N-1 to N (which is previous
cooker versions), maybe we can erase it. And only have history from
N (release date) to N + updates.

Yes.

The advantage is that it is easier to implement, and already implemented
now in a repsys branch on git. But it is still possible to replace the
SVN binary repositories with something else later.

</I>
Removing something from SVN is not very difficult, if removing all
history before a commit (and not only some of the files).

</I>
It can be a good idea, but it requires some work to implement it. I
think it's something that can be done later.
