Indeed, that's a valid opinion. But the problem of missing patches for these older branches is more or less home-made, since it was simply forgotten to merge the existing patches to these branches. So it shouldn't be that much of a deal to catch up, since voting can be omitted in most cases.
I'm willing to push patch sets for those issues that seem to be forgotten (thanks to Ernesto for his tool).
