Obviouly, these are mostly happening at a firewall or equivalent, which is kind of the point. Very little DPI is legitimate in core networking.

I would not limit your point to core networking. DPI technology is also used by organizations at the networking edges to conduct censorship. I agree that there is some legitimate use for DPI but giving up on that is a small price to pay considering the mass surveillance and censorship which is made so easy by DPI.
