Then we end up with profiled CQL as to which bits each implementation has
to support. CQL Profile, part A level 0: Must support searchClauses and
Triples. Level 1: Must also support prefixes. ... Urgh.

Why not? That sounds like an interface design issue, not a protocol one.

Assuming that the default index of the client interface is different from
the default index of the server. And then at the server end it's extra
work for the server implementor to process, as they will probably have to
go through and add in all the defaulted indexes.
"So Don't Do That Then."
Why would a user enter CQL fragments into a search box which has an index
anyway? Either have them enter the entire query, or have drop downs for
the index and one term per box.

My point is that CQL structured terms are less useful than something which
has been rejected for not being useful enough to include.

They might do that, but they could also enter SQL queries or PQF. If you
want to have an interface that turns SQL, PQF or CQL fragments into CQL
then be my guest, but I don't see that it's necessary for the protocol to
handle it natively. What if they meant to search for 'keyword and
author=jensen' as a freetext search term? Still need client side logic and
