Here's another, related but more radical (and rather unbaked) idea:

Move all the kernel modules and their associated libraries (thinking of 
KNI here) to a separate repo with perhaps more relaxed rules, but OTOH 
require upstream kernel support for any features to be included in dpdk 
itself. Carrot-and-stick of sorts :)
