Wow - I am surprised that I never noticed that. I am looking around and
noticing them in lots of applications now (Finder, Office, TextWrangler -
all the applications that interact with file system objects)

I found a posting (refer
http://mozdev.org/pipermail/camino/2003-July/000071.html) that implies that
you could get a handle to use the Carbon API (refer
http://developer.apple.com/documentation/Carbon/Reference/Window_Manager/win
d_mgr_ref/chapter_1.2_section_10.html#//apple_ref/doc/uid/TP30000176-DontLin
kChapterID_2-F09074) - but as you say this would probably be considered bad
form.

My vote is to stub to an empty subroutine

Personally I don't think that would be a good fit in general.
