That's great; the point that I was trying to make was that while there are indeed bug fixes in the patches, they're latent bugs because there are no current users in the tree.  So there's no need to hurry up and get these fixes in, they can wait for 4.10.  I don't think your patches will run into these bugs either because you don't use tags.  I do think that Kirill's patches might hit them though.
