The usual issue mentioned is that Cocoa plugins can't be unloaded and PS
does unload plugins. See for example this thread:
http://www.cocoabuilder.com/archive/message/cocoa/2005/11/30/151472
There are a number of other threads in the archives discussing unloading
plugins and PS plugins.
Use of categories is problematic. Also, I'm unclear on whether things work
as expected if multiple plugins use the same class names or same category
names and are all loaded at the same time.
Also, obviously since Cocoa is Mach-O only you won't (easily) support older
versions of PS.
I assume that with the next release of PS, or the next release of the PS
SDK, Adobe will either explicitly support Cocoa plugins or will have a
stated policy on such support, which is currently lacking.
