Has this idea, or one like it, been proposed before?

there are lot of error handling simplification proposals but this one is very simple

Does this affect error handling?

makes it shorter and more readable

Is this about generics?

No

Besides the default

if err != nil {
}

Allow also for an easier and more readable:

if err {

Yes

Would this change make Go easier or harder to learn, and why?

Easier
