If someone with real authority ever complains, then the code could be
backed out again.  Your opinion seems not much more informed than the
rest of us discussing this.

This is almost certainly not going to be used by regular end-users.  It is going to be
used by public safety organizations who are buying equipment from companies
using open-wrt, LEDE, or similar, or possibly small teams at public safety
organizations doing the work themselves.  Rather than having each of these vendors
hack their own crap into their kernels or forcing the the organizations to use Cisco gear,
we could work on it together.

Anyway, if upstream is blocked, then maybe we could work on getting this into LEDE?

Thanks,
Ben
