The answer is “sort of”, over time. David started the Aquamacs project
in the very early days of Mac OS X, with a principal goal being to give
Mac users a more Mac-like experience for Emacs. Over time, the code
bases diverged as the main Emacs distribution got a lot more work done
on the Mac version. There has been some back and forth over time, but
still a number of subtle differences.

So today Aquamacs consists of:
1. A set of changes to core Emacs C/Objective-C source code and elisp code
2. Non-core customizations and elisp code for the more Mac-like experience
3. A set of pre-installed packages of special interest in the Aquamacs 
community,
        such as AUCTeX and ESS.
4. Additional documentation, and probably a few things I missed

It would be great to get to the point where #1 is the empty set, or at least
very, very close to it. Then Aquamacs can be more of a specially packaged
distribution of Emacs on the Mac, and the Aquamacs community can
more easily benefit from and contribute to the main Emacs work.

Other thoughts on this welcome, of course!
