So i strongly feel that a great goal for Oxwall and developers alike is to be able to achieve something like this in the years to come. And to have the staff to enforce it.

Understanding that even this is not a perfect system, but IMO WP has set many standards for others to follow and they have set the bar pretty high.
I don't expect we will achieve all of this in the next few years, but maybe in 10 years or less. And any improvement is an improvement in the right direction. :)
