I wasn't particular concerned with the full access part, but with
bypassing the group protection layer in general.  This layer is used
to make it possible to hand over parts of the hardware to selected
programs to do their low level things without handing over the entire
machine. It's also used to give individual users access to selected
programs and hardware parts.  Thus deviding and restricting access
helps managing security.

One can argue what the relevance is for say a cdrom, but e.g. for
disks it would be dramatic (giving all more or less root access).
Once people start circumventing it for simple things as sound, discs
will follow (IIRC even adviced on this list, though not recently)
