Hi,

I will just give my thoughts on this, but since this port is a  
community project it is not necessarily my decision what to do.

The reason to prefer command = command is that emacs can then use  
similar accelerator keybindings to other os x apps.  The reason to  
prefer command = meta is that emacs can use similar non-ascii latin  
character entry to other os x apps.  Which is preferred for a given  
user depends on two questions:

1) is the user in continental Europe?
2) is the user editing code or text?

Why (2)?  Now that I've been living on the continent myself for a  
while, I've noticed that programmers here often just use a US  
keyboard layout even if they have a physically non-US keyboard.  It's  
just too much of a hassle to get commonly-needed special characters  
otherwise.

So my feeling is that the command=meta option is preferred by text- 
writing Continentals, while command = command is likely preferred by  
everyone else.  I am not sure which group makes up a larger subset of  
OS X emacs users.

I do know that I received a few complaints over the years from folks  
disliking the Emacs.app command=command default.  My answer was  
always to rehash the above and note that it's easy to change it --  
just flip a combo box in the prefs panel.  Now that it's not so easy  
(I guess figuring out the existence of ns/mac-command-modifier  
variable and writing suitable elisp to .emacs is necessary), the  
default setting becomes more important.

I agree with both of these.  So perhaps the best default would be  
command=command (super), alt=none, and the user can set a meta key  
(additional to esc+) if he/she desires.
