Yes, you can still use them, but they are certain to go away.
Actually, stand-alone UI apps *had* to have a resource fork in OS X
or they would never get activated or brought to the top. There is
documented interface now to get around this. "TransformProcessType()"
and "CPSEnableForegroundOperation()".

Yes, creating eternal chaos. If you were to copy a file by name, the
resource fork would not be copied. Even the original OS X "tar",
"cp", "mv", etc. commands (until 10.2) did not know about resource
forks and destroy applications. This has cost us endless headaches
and many support calls to the point that we almost abandoned OS X
support altogether.

The command line "ftp" that came with OS X did not do that. I have
not checked after 10.1, but I doubt it would.
But hey, I am drifting off in my flu-fueled rant ;-)
All I wanted to say originally was, that we need to be very careful
when converting .sit archives to .zip archives as we may lose some
essential information. NTK project files for example store most
project settings in the resource fork.
