Not sure how you got this information but this is not accurate.

The position Neutron has typically taken over the years is that as
community we work within the constraints and the dynamics of the various
open source projects and solutions that are required for building
networking abstractions, taking especially into consideration when and if
certain technologies are mainstream.
To your specific reference to NSH and SFC, we strive to define abstractions
that are not particularly tied to a specific technology choice; that's step
1 in providing technology agnostic networking solutions; step 2 is to
experiment with the above mentioned abstractions by building open source
solutions that are readily available. When there's a lag, we wait (look at
how long it took us to have either DPDK of OVS connection tracking enabled
in Neutron for instance).
Having said that, that does not stop anyone to use and provide feedback to
those abstractions agreed at community level and build on top of the most
disparate stacks that are out there.
So what exactly is that is concerning you? I am confused.
