Apart from the objections raised by Richard I've found 2 other problems with it:

1) it will force a cache invalidation each build
2) fetch2 witll *always* try to access the remote git repo, even if the SRCREV is already present in the local copy

Those aren't really bugs in my patch, but in the rebasable fetch2 code.
