Anyway I remember reading somewhere that Apple warned about
relying on ..namedfork/rsrc always working. I can't find the
reference at the moment though.
That was WWDC 2006, in which the speaker for one of the sessions
commented that the /rsrc hack was going to be removed from Leopard.
It didn't say anything about ..namedfork, though - just /rsrc,
which I don't think anyone really uses anymore. Of course, /rsrc
still works in Leopard, so who knows.
Here is the reference I was thinking of, but I was wrong:

Also, the kernel did not provide stream access to the resource fork.
You could get and set the resource fork via the extended attributes
API, but you could not open a file descriptor to the resource fork on
all file systems. The "foo/..namedfork/rsrc" trick would work on
volumes that supported the resource fork natively, but would not work
on volumes that stored the resource fork in an AppleDouble file.
o In 10.5 we got rid of the File Manager's AppleDouble code. File
Manager now (more-or-less) treats all volumes the same. The
implementation of the native/AppleDouble abstraction layer is now
done entirely within the kernel.
This means that, when you access metadata via BSD APIs, you're
accessing through exactly the same API that File Manager uses.
Neat-o! It also means that you can do the "..namedfork/rsrc" trick
on all volumes [1]. For example:
So the situation actually got better and it seems that ..namedfork/
rsrc is now supported on all volume formats. Sorry about the confusion.
