> If you accept their garbage bytes, things might seem less broken in the short term, but then every implementation is stuck working around some fool's inability to follow directions forever, and the protocol now contains an artificial ambiguity because the bytes they put there now mean both what they're supposed to mean, and also what that implementation erroneously uses them to mean, and it might not always be detectable which case it is. Which breaks things later.

And, if your project is on GitHub, gets your Issues page absolutely clowned on because you're choosing to do the right thing technically and the leeching whiners shitting up the Issues don't want to contribute a goddamn thing other than complaints, and they definitely don't want to go to the authors of the thing that doesn't work with your stuff and try and get that fixed either.
