My current understanding is that where the OS conventions for keys
to operate something are the same, that we should have the ARIA keys
follow that desktop precedent.

The motivation for this is that the desktop look and feel development
is more mature than the WebTop equivalent.  The web exploded
on just point and click, but the need for richer action options
has re-surfaced as the web takes on bigger and bigger jobs.
Designers writing widget scripts seem to be trying to emulate
the desktop look and feel; we don't need to fight them to make
that look and feel accessible in the web applications.

Where there is no stable and cross-platform usage for some function
we need to complete access, I was hoping that then this group would
undertake the role of inventor for something that ought to blend in
well with the established keystroke conventions.

I would prefer that where the operating systems differ, this group
does a case-by-case choice among the precedents.  Although the
bulk of the decisions may emulate MS Windows, I would prefer than
you not make that a blanket decision up front.
