The irony is that the edit is entirely correct, and was made by one of the most knowledgeable people in the universe on the topic - a core meteor developer, @avital. While the reviewers were trying to be helpful, they unfortunately lacked specialized knowledge.
How can we fix this systemic problem? Here's the best idea that surfaced (thanks @bart):
Propose reviews on edits only to users who have at least one of the question's tags.
Other ideas are below:
Do make use of that "Skip" button if you're not sure about an edit
Providing a mechanism of notifying reviewers that their rejections were mistaken.
- it discourages highly knowledgeable (but new to SO) individuals from contributing to SO
- it reinforces the sentiment that reviewers have absolute rejection powers, despite lacking specialized knowledge
- it perpetuates incorrect answers by rejecting useful changes.
How can we fix this?
