There's nothing in IPsec that knows about TCP connections now, and there

There might be utility to coordinating TCP with IKE, but that means that
the SA used by a packet needs to be set explicitly by the upper layer
rather inferring it from policy rules.

I.e., TCP may need to know about IPsec, not the other way around.

Connection latching should, indeed, be initiated by TCP -- but that does
not mean the matter shouldn't be mentioned in the IPsec architecture
doc.
