but old binaries still no longer work?

that seems like a binary compatiblility issue to me and you
should change the kernel to make them work again, not change
userland to match some new kernel thing, particularly where
the change itself was debated considerably and not espcially
necessary for existing OOB using code and no new code should
be added...
