The fact that we are using wired Ethernet vs. WiFi is generally not
visible at the level we're doing this identification either.

If it does not matter to the protocol semantics, then I believe it to
be safe to use the same identifier for two similar-but-not-identical
stacks.

Yes, one might argue that TURN-TCP encapsulation is tangibly different
to non-encapsulated SRTP.  We can talk about those distinctions and
whether they require different identifiers, but in this case, I don't
see any need for distinction.
