SRU/SRW/Zing is still a moving target. There is a quite a bit of
discussion about the purpose of that protocol. The direction so
far looks promising.
My point is that the current OAI list design is unsafe, not that
I would like it to work differently.
LDAP, SRU, and every web search engine use the model I suggested.
The model in OAI is dangerous to clients.

Yes, though I would be happy if OAI focussed on metadata access.
General search is a different problem.
