Simple for developers
That quote is suggest to be in the most WordPress development project we lead, we respect the regular user, but we focus most on the developer point-of-view. One simple example of what it means on our wp plugins is most of then don’t have an wp-admin options panel, you must edit it directly on plugin folder.
WordPress community quick reject that way of doing projects because when you update it, you lost the changes. That can be really a problem, but we suggest you just fork our projects and be the owner of your own custom solution, it means stop receiving or updates, for good or bad.
So we came back to original quote, simple for developers!
