The only one ever looking at my default browser cache is me, so I really don't care if it's cached. Anything on me that's going to be caught by a third party occurs via the URL or headers anyway and are outside of my browsers control.
Just came to say this: Wefwef provides the best experience for Lemmy. Honestly this app should be blasted everywhere. No other frontend competes (including desktop).
The funny thing is that dev recommends to use Watchtower if you wanna selfhost this web app with Docker, which is what I do, but I have my Watchtower set up to do daily checks, and that clearly is not enough for Wefwef lol.
