No, because not everyone reads PRs. And at this point you're complaining about the 30 seconds it takes to open a ticket and copy & paste. You still haven't provided a reason why that tiny effort is not worth the bit of value it provides. And frankly it just sounds kind of ridiculous at this point.
There are plenty of comments that do a much better job explaining why a context switch isn’t just 30 seconds in this example.
Besides if all I’m doing is taking 30 second to copy and paste something what value is that really adding? If nobody says anything the docs stay incorrect. But when I want to fix an error I need to context switch and open a ticket and copy and paste what I already wrote once? I’d rather just do nothing.
Really though, I’d rather just have up to date docs, so let me update them instead of insisting people do things your way. Fix the problem with people not being able to see the PR, don’t make me do the same thing twice.
