I don't need your help. You need it. I'm helping you realize your statement is wrong.
First you make a statement saying one should read all the docs. Now you say devs should read the relevant docs. Devs do the later anyway. Your argument just evolved into the point you're arguing against.
Clearly you didn't mean to do that. You just meant to read more docs then you normally would on topics a little further from the relevancy at hand. But people are responding to you based not off what you meant but what you said.
