If someone has a big runaway log file open that is running you out of
disk space, and you remove it, then it goes away. That's a feature.
(Of course, we don't have this problem on the worm drive, but the
point stands.) This way is simpler, and I've yet to see a compelling
argument against it.
You're right that the kernel doesn't care -- the file server is giving
you the phase error. Many of the non-disk file systems do reference
count their files.
