Yes. This is in the CDI spec, so can't be removed right away, we need to support this for at least the next revision.

No.

This wouldn't work for CDI due to backwards compatibility.
Instead (or as well?), could we offer a registerNamespace() method (similar to how we are handling imports)? Then EL will have a static list of namespaces that an (optional?) namespace resolver could resolve against before other resolvers are used. CDI knows namespaces at startup so could register all it needs.
WDYT?
