Serious question: how important is `pip search` to your workflows? I don’t think I ever used it, back when PyPI still had an XMLRPC search endpoint.

(I think the biggest blocker on CLI search isn’t infrastructure, but that there’s no clear agreement on the value of CLI search without a clear scope of what that search would do. Just listing matches over the package names would be less useful than structured metadata search for example, but the latter makes a lot of assumptions about the availability of structured metadata!)
