I suspect that your view as an AD may be more nuanced than mine, but I
must admit that I am not entirely comfortable with limiting ART to
"human communications", as would be implied by the text as currently
written.

Certainly nothing in rfc3261 explicitly limits communications to humans.

I believe that dropping the phrase "among humans" from the paragraph
does not impact any aspect that at least I can observe, and may indeed
have the benefit that no one in the future will claim that SIP cannot
be used for m2m communications because of the limiting phrase.
