I think there would be little or no controversy with this approach, as it’s much less disruptive to the overall community.

Yes, this is a variant on the "external dependency" approach that would 
address most of the community fragmentation concerns by keeping the 
optimized parts small and Python-driven.

I could see that working for Designate's MiniDNS (and other partial 
optimizations), but I'm not sure that would work in the Hummingbird 
case, where all the node is rewritten in Go. If we mandated that 
approach, that would probably mean a lot of rework there...
