Coming over from #7124 (comment), quoting @bradzacher:

... we've always given the advice that you shouldn't do progressive enhancement of lint rules depending on if type information might be there.

Thats the same hard-and-fast rule that we have taken with every single one of our lint rules.

The reason we take this line is because config is hard and if you just silently enhance a rule with type information but the user misconfigures it how can you alert the user to the misconfiguration?

This is good advice, but I don't believe it's in the public rule docs? We should add it so folks know. This comes up once in a while on social media too.
