If adopted, this will be:
DOSed to death
Falsely reported by people who aren't qualified to know a true bug or give replication info
Cost more than it's worth to separate the wheat from the chaff.
I'm sympathetic to getting real bug info to the right place more easily, but I don't see how this solves anything much - there are reasons, some listed above, why manufacturers don't already make it easy for any random person to waste the time of their developers.
Obviously, the manufs have gone too far here and just ignore it all, but any real solution is going to have to have someone "watch the watchers" and come up with money/effort to do the screening.
