In reply to Julie @Niackery.

I want to come to the defence of "wayward developers".
A lot of stuff goes into the plugin repository.
Some plugins certainly merit a well thought out submission.
Folks want to do all the aforementioned practices.

But other plugins are outliers for many different reasons. Many require actual code investigation.
Those plugins should have unique standards and when researching them one should take this into account when evaluating a plugin page.
