We do try to bend over backwards on ABI issues if it really is noticeable for applications. Now, in this case, if you can just fix your app to not care (because it really was badly written in the first place to even notice), then that is the _much_ superior solution. But if you actually have binary-only commercial apps that break, we'll do a compatibility thing rather than the 0 that already got merged. Although I don't really even see what we can sanely do except for the 0 case. We could put the virtual address in there instead of zero (I forget what old kernels used to do - whatever magic value the anonymous mappings got, it wasn't really designed as an important value in its own right, it was designed to trigger the "we can merge these vma's" logic.
