It doesn't fully remove YT Shorts, but it is helpful and I left it installed for a week or two because it does at least redirect you to the full-page YT video for the Short.
The reason for my uninstall, and lower rating, despite not actually fully removing Shorts, is:
This extension interferes with CTRL+click (or middle mouse button click etc) on any regular YT video from your feed or front page or anywhere on the site, and doesn't open a new tab. Not every single time but it's like 3-4 out of 5 tries for me, which got really frustrating after a while.
