Back in 2020, Discourse switched from the .js.es6 extension to .js. Over the years, the vast majority of themes and plugins have switched to the new extension, which provides much better compatibility with modern JavaScript tooling.

I understand that this change is frustrating and I would like to find a path to maintaining these plugins if they’re important to the sites using them, specifically so we don’t end up with broken functionality.
