Lastly, for the code maintenance, I believe this memory allocation keeps
the code much simpler than it would otherwise need to manage a special

Yes, I can see a simplicity as a reasonable argument for a quick fix,
which these pile is supposed to be AFAIU. So this might be good to go
from that perspective, but I believe that this should be changed in
future at least.

So the conclusion is, that we ship this set of patches now to cure the
existing wreckage, right?

Fine with that, but who will take care of reworking it proper? I'm
concerned that this will just go stale the moment the fixes hit the tree.

Thanks,
