The key phrase here is "Magnification relies on Orca now to provide

Already, GS-mag does not require Orca; GS-mag can run "stand-alone".
One can do relatively simple changes to preferences such as
magnification factor, cross hairs, mouse tracking modes, and viewport
position, all without Orca. But, it can't do anything as complicated as
focus tracking. At this point in its development, it's fine to rely on
Orca for that, since there is more important intrinsic magnification
functionality to implement (e.g., colour inversion). But, requiring
Orca for focus tracking strikes me as a relatively heavy-weight solution
in the long term -- as a user, if all I want is to magnify the UI, but
don't care about speech, nor braille, nor other screen reader functions,
why should I have to launch Orca for decent keyboard access?
Also, I don't understand what problem you're trying to solve. Magnification
relies on Orca now to provide focus details; what practical problem does this
introduce, and might there be other ways of solving it that don't involve
separating out code and functionality in the proposed way?
Also, although this thread is about focus tracking and magnification,
focus tracking can be thought of as a more general issue. It is a
perennial a11y/AT problem: where is keyboard focus now? where was it?
where is going to be? If there could be a general solution, that
everyone could tap into, that would be a Good Thing(tm). But, perhaps
that's pie in the sky.

It's deeply integrated into the Orca scripts specific to applications. While
it could be abstracted, I assume this would involve writing separate extension
modules per application
Are those specific to applications in general? Or specific to specific
applications -- a script for FireFox, another for OpenOffice, and so
on? If the latter, then I agree that it would be very difficult, if not
impossible, to create a separate *general* focus tracking module.
