A javascriptless check was released recently I just read about it. Uses some refresh HTML tag and a delay. Its not default though since its new.

As long as its not configured improperly. When forgejo devs added it it broke downloading images with Kubernetes for a moment. Basically would need to make sure user agent header for federation is allowed.

I don’t know what makes roundabouts so hard that 90% of people stop in my town when nothing is in it instead of yield like the sign they had seen in their drivers test.

I like your ideas.
