"SIP-only accounting is "good enough" most of the time."
Does not work in production environment. Specially when you are charging per second or per minute.
Works only if some one is offering unmetered only service or just doing it for fun. If it metered service like calling cards, termination or metered DID etc, then this can be really bad.
My 2 cents.

Yes.  There are some liabilities with that in that the signaling
messages may be incomplete (i.e. you may miss a BYE) and this is the
usual reason given for doing media proxying for more accurate accounting.

But the latency, bandwidth consumption, and increased complexity and
cost associated with doing it on a large scale does not justify it, in
my opinion.  SIP-only accounting is "good enough" most of the time.
