Yes, it currently does appear to be a small team :-( Maybe it will get
larger once the core is nearer to completion.

Can you elaborate on what you mean by this ? Are there API issues (other
than the ones deferred) or is this referring to an implementation to go
with the API ?

Step by step but not necessarily serialized unless resources dictate
this.

This ordering makes sense to me, At the point there is a (kernel) CM
API, the kernel ULPs are "enabled" (SDP, SRP, kDAPL). Hopefully we can
be more parallelized by then.
