I've been using this for some time. I noticed that it works with Troddit, my favorite Reddit web client https://www.troddit.com/, you just need to go to custom and add it there.
I use it mainly on Android with kiwi browser so I don't need to download apps
For Reddit I've just been relying on uBlock Origin to block trackers, with some custom rules to get rid of all the superfluous sidebars, header bars, banners, avatars, achievement icons etc. The cleaned up interface actually looks very similar to Troddit's "Classic Rows" style.
