This is another one that I had already addressed in a somewhat inferior way.
I attempted the same kind of cleanup that you did in patch 2/3 but failed to
convince myself that I had managed to avoid regressions, so my patch just
copy-pasted the native implementation into the compat handler with minor
changes.
Provided that your preparation patch is correct, this version is clearly better
than mine, but again I don't know the state of that patch after Sam had
said he applied it already.
