I don't do it by default, for three reasons: (1) it's more expensive, (2) I actually quite like seeing the derives, and they may expand to no impl/more than one impl, (3) if #19130 will ever be merged this will become even more useful.
Even a config might be too much, but it was fun and easy to code so I did that. CC @rust-lang/rust-analyzer - feel free to close this PR if you think otherwise.
Closes #20016.
