Overview

[JoshuaKGoldberg]

Agh, sorry, I was incorrect when I indicated array-simple would be an ok rule setting to take in. I was mixing it up with the default one that prefers T[], which is this repository's preference.

IMO Array<T> should be a discouraged construct in the type system because:

• It's extra characters to achieve the same thing as T[]
• JavaScript usage generally discourages Array(), with [] as the preference

Closing this PR as non-actionable.

I know it must be annoying to have a change indicated as favorable in one PR and not in another, my sincere apologies.
