Thank you for the pay attention on this issue.
I know that you constantly ask about it, especially core-team members :)
I appreciate it, because it's really helpful and more over important.

Unfortunately new approach with empty reverify made people more lazy.
I think, that we should follow your recommendation, because:
 - it will help fix our gate faster
 - makes our develop process more clear and useful for new comers

my +2 for this initiative.
Everybody please spent your 2-3 minutes to make our work better!
