I appreciate how frustrating it must be for you and other competent
developers, but the reality is that as browser developers, catering to
"average" developers (and preventing them from causing damage) is something
we have to worry about a lot.

We have to be careful about logic like "developers who use this API will
know what they are doing", because it's normal for developers to
copy-and-paste code that they don't understand and tweak it until it works.

“You have heard that it was said, ‘Love your neighbor and hate your enemy.’
But I tell you, love your enemies and pray for those who persecute you,
that you may be children of your Father in heaven. ... If you love those
who love you, what reward will you get? Are not even the tax collectors
doing that? And if you greet only your own people, what are you doing more
than others?" [Matthew 5:43-47]
