This is actually a more general requirement (which we may have discussing in
passing). Any user-defined class instance that JSF creates should be
classified as a components in Java EE. But, to accommodate that without
tying JSF directly to the platform (a separation we have always maintained),
there should be a pluggable class instance resolver which could be satisfied
with a CDI implementation, a Spring bean implementation, etc. That way, it
would be possible to support CDI injection into objects such as phase
listeners, system event listeners, validators, converters, and so on with
the proper resolver. Basically, any time JSF accesses something w/o the use
of the EL, it should go through this instance resolver.

In a way, this complements the EL resolver, which is already a nice
mechanism for hooking into different component models.
