I've written a program (on a Mac Plus) that uses the new zoom box on
its windows.  I tried it out on an old 64K ROM system with Finder 4.1
(and the associated System) and found that there were no zoom boxes
(expected) but that the grow box didn't work either. I haven't investigated
it further, but apparently the window manager was not sending a inGrowBox
message to my event loop.  The grow box worked fine with System 3.2 on the
old machine.

Is this a known feature?  If so, how can companies make software work for
both computers when the 64K ROM Mac's are instructed to use the old
System?

The WDEF resource in the old System does not understand the modifier
bit that specifies a zoom box, so it sees a window type which is out
of bounds.  It chooses noGrowDocProc as the type of the new window.

I encountered this problem with UW.  My "fix" was to check ROM85 to
determine which ROM set is in use.  If the old (64K) ROMs are in use,
it turns off the zoom-box bit before calling NewWindow.  (It doesn't
matter if the WDEF 0 in the System file really does know about zoom
boxes, since the Window Manager in the old ROM can't handle it anyway.)
