What scale of frontend apps do you work with? Specifically, how many developers are simultaneously writing features and merging code in a given week?
But I have, in a fairy large project (completely rebuilding all of Deere & Co's internal systems, upgrading from literal terminals to web app) with >100 developers merging in hundreds of PR's a week.
We've never needed something like this.

I think that site could benefit from something like this. The CSS on that site is, um, not optimized.
Do you ever just re-read your replies and think "I'm being ridiculous" and decide NOT to post it? You should do that more often.
