Well, my issue with this is that it has only some 'hard' hints for P0, P1.  It doesn't actually say much about P2, P3, P4, P5. In practice we tend to but a _lot_ of stuff in the P2 bucket, and don't use P3, P4, P5 that much.

Some stats to back this up: Here's the numbers of unresolved Qt bugs that affects any Qt 5.3, 5.4 JIRA versions, split by priority:

P0: 3
P1: 139
P2: 847
P3: 428
P4: 90
P5: 7

So, we've more bugs in P2 than in all the other buckets combined! Ideally we should spread this out somewhat more, to have a better visibility of things that are important, and things that aren't _that_ important ;)

Fair enough, nobody is of course forced to use this ;) I'm personally always a bit confused what is a P3, P4, P5, that's why I started this.
