In the month of July, 15% of Aquamacs users were still on 10.5, and now 10.7 
has come out.

However, if you only look at people who have recently (within the past two 
years or) have upgraded their installation to one based on Emacs 23 (from Emacs 
22), this figure drops to 9%.  Among the users of the latest version of 
Aquamacs at the time, it's 7%.

Given that Emacs has very limited resources in terms of OS X developers, this 
suggests to me that supporting certain features only on newer OS variants is 
warranted; dropping support completely for 10.5 is probably a little early.  

The GNUStep argument may be a stronger one from an ideological standpoint.

As I've said before, feel free to take the Aquamacs code (which is based on 
typester's patch, combined with support for the standard frame parameters) and 
turn it into an Emacs patch.  Let me know if I can answer any questions.  (Y. 
Mitsuharu's 10.7 code sounds great, perhaps it can be used or reimplemented for
