Yes and no.

There is precedent for doing some work early, but gating it on kernel version.

https://sourceware.org/glibc/wiki/Style_and_Conventions#Support_for_features_not_yet_in_the_mainstream_Linux_kernel.3F

So you could use kernel-features.h to disable the code until some future kernel
version puts it in place.

Cheers,
Carlos.
