It will not do anything for device nodes. For network devices NAME= still works.

Still, the DVB devices can not be renamed, only additional symlinks be created.

But honestly, the apps should just enumerate the stuff on their own.
There are not many legacy apps needing DVB signals, I guess, where
such symlink games would be too useful.

The udev symlinks are mainly for things that expect predictable names
for legacy reasons, or for tools that are too simple to cope with
modern systems. DVB applications should not really be in that
category.
