You're right, this was an assumption on my part. If you do this for a file that's on the desktop, the Finder will turn the icon gray. You see this most often when using a (well written) browser to download a large file. I had simply assumed that the interface was universal, and that all "bzy" files were displayed with a grey icon everywhere. I guess not. Maybe in Tiger.
Regardless, I stepped through to code and stopped the program at the point where the files/folders are being created and the Finder will refuse to trash any file that has a type of 'bzy', so that much works even if the icon doesn't change.
On the other hand, a folder with a create date of kMagicBusyCreationDate doesn't seem to make any difference. I'll leave the code in there (because it doesn't affect my program) in the hopes that it will be better supported in the future. Maybe I'll file a bug report. (This is in OS 10.3)

I'll put that on my to-do list. This would, at least, give me much more control over the icon while the file was being written.

Finally, something to bring with me to the next WWDC!
Cheers,
