Thanks, I think it's worth to re-iterate why:

The most directly visible problem is that this breaks the
/dev/disk/by-id/ links - all devices would have to point to the same
one, and which one actually shows up is somewhat random. This basically
means random corruption if people actually use the links or the uuid
functionality in any other way.
