Must have plugin works in WP 5.4.2 (July 2020)

This is a must have. WP guesses the most wild things without it.
I found thousands of random urls on google, none exists. This plugin makes them 404. like they always should.

A new hook will be added in 5.5
add_filter( 'do_redirect_guess_404_permalink', '__return_false' );

WordPress 5.5: Better fine grained control of redirect_guess_404_permalink()

Until then. Must have
