What does this mean? It seems like as the author of a prototype SQL
implementation, you'd have a unique view on where (3) should lie.

Sorry, that was supposed to be implicit. If we have abstraction layer
(1), then layer (2) only applies to the implementations which follow the
current implementation fork, and likewise if we have distinct
abstractions at both (2) and (3) (as CMike wishes to avoid), only
implementations which follow the current implementation fork at (2)
would be participating in the abstraction at (3).

This document has the same problem as your "master patch": it's 31 pages
long and hard to digest. We really, really need your contributions to
this process to be concise, focused, and objective. If we're arguing
about a particular aspect of FS abstraction and you have an opinion
about it, we need you to give your opinion about just that one question,
not say, "I've been working on this big document with diagrams over here
and part of it talks about that; please go read it."
