Edit: I meant to add, thanks for a well written and easy to read

Some minor comments:

-4.1: This is the first mention of "credits", and there is no definition.
I realize that the term is defined in the reference from the previous
section. It would be helpful to mention that in the context of that
--  Are there any head-of-line-blocking issues introduced by
bidirectional transactions? For example, can a reply get stuck behind
requests that are blocked by flow control?

-5.4, 4th paragraph, last sentence: Can a reverse requestor reasonably
give up or time out, rather than wait "indefinitely"?

-8:  This implies that reverse direction transactions do not change
anything.If that is the case, please say so explicitly. For example, Is
there any change to authentication for reverse calls? I am not an expert
in direct memory access transport protocols; are there every situation
where authentication depends on an initial request from the client?
