From what I can see in /lib/udev/rules.d, the ids files are only used to setup
the (udev) environment variable ID_VENDOR_FROM_DATABASE
(75-net-description.rules, 75-tty-description.rules, 78-sound-card.rules).

There are no symlinks created in /dev based on that information.

Given the name of the rules file, it indeed looks to be intended to be used for
display/descriptive purposes.
