I'll interpret that as a confirmation that they don't tech the value of
field testing, much less market analysis, in network engineering classes.

Are you assuming consumers will simply open up their firewalls and let
(your) protocols through without inspection, were NAT out of the way?  I
just don't see end users giving SRTP or any other protocol a free pass,
regardless of firewall gear, regardless of NAT.  Also doubt that the
alternative packet inspecting and/or other ACLs would be simpler than

You might float your idea for making network engineering easier (by
killing NAT) over on the firewall-wizards mailing list.
