The cross platform icon editor could use both ICO and ICNS files. My example
was talking about the end _user_ perspective. If they want to create ICNS
files, the fact that your editor decided to "use ICO instead" doesn't help them.
I also don't see how "outside of OS X" is even a concern when the code's
already written and tested and doesn't depend on anything except the jp2 plugin
(and certainly not any native APIs). Specifically making it not work outside of
OS X would require more time and effort for seemingly no reason. The plugin is
barely 400 lines of code, you wouldn't be saving much by switching to native
APIs. You'd either offset it with overhead from Objective-C APIs, or end up
simply having the same amount of code from the verbosity of the C APIs.
Furthermore, a comment in Mikkel's source appears to indicate that GDK-pixbuf
supports ICNS, and if GNOME (which doesn't have very good OS X support and
integration, especially compared to Qt) supports it, I don't see why we
shouldn't. Besides, this is targeted for an optional, non-essential module. If
you don't want the very minimal overhead of the ICNS plugin, just don't build
it, and/or don't deploy it with your app. It is my understanding that is the
whole point of the QtImageFormats module in the first place: to support
optional, lesser used formats.

We have TGA or WBMP support - does anyone *really* use those? At least we can
say with a straight face and reasonable conviction that ICNS support would be
useful.
