Just creating a second newer header package would be relatively easy to 
implement without much rebuilds. (basically only all kernels which are 
already being rebuild weekly).

The more general problem is a bit more tricky though:

I agree that it is a bit confusing that there is an unversioned 
linux-libre for the the latest kernel but the unversioned header is some 
arbitrary version.

The main part (i can see) where linux-libre-headers are used apart from 
the bootstrapping process is being propagated from glibc and therefore 
being included into *every* build environment (apart from hurd). So in 
terms of rebuilds basically everything.

Have a nice day,
