I used an extension a while ago that changed CSS colour values (#ababab) into little coloured dots, that became a colour picker when clicking on them (while still letting you input RGB or Hex, ofc), and it was pretty awesome!
So, I could unironically see this being really nice. Although... I think this would need a pretty narrow context, something like if x == true would look pretty confusing as a toggle, I imagine. But assigning x = true? Bring it on.
Personally, I'm subscribing to the belief that the fediverse's attribute of "true censorship is impossible" is a benefit, not a curse. Every prior example of censorship has just morphed into "advertiser palatable". Which is bad for everyone.
More than happy to have access to instances that will take the kind of drastic action you're suggesting, access to my own "block" function, etc. Let them come.
The fediverse will inevitably host some messed up stuff. Counting it a blessing that those people have a clear place to go to and sequester themselves off.
So ultimately? More than happy to have an instance that agrees with this extreme anti-censorship posture. Sh.itjustworks is fine in my books. I can block the community, just like I could block subreddits on Reddit without abandoning the whole platform. Hell, even write a script to block everyone who's subscribed to the community. The power is yours now, and nobody can take that away. That's the fediverse.
