I agree with both your points.

Nevertheless, it is easy to get channel variables set on the channel
for things like the username.

For instance, the "setvar" option in a SIP peer/user/friend entry
allows you to pass on the peer that the call came from.  (And/or,
"accountcode").

I have a little macro I use to wrap around SetUserField, so I always
stash all this extra data into the CDR record too.
