The problem I see with depending on notifications is another one of those
"looks good on paper" things: For whatever reason, support for sophisticated
handling of notifications has been slow to materialize in user agents.
Agreed. OTOH, since the client is going to have to handle CONNEG in
any case, adding a notification parser to the mix as part of the
CONNEG implementation is a different issue since it is not adding the
notification parser to existent support but adding new support that
INCLUDES a notification parser as part of its implementation
requirements. Note that I am not advocating or rejecting a
notification parser solution but only pointing out what I perceive as
a fallacy in your analysis of the issue.
