I change var to let in my first try. But I got
/home/travis/build/nodejs/node/lib/_http_outgoing.js
802:8 error Use of `let` as the loop variable in a for-loop is not recommended. Please use `var` instead node-core/no-let-in-for-declarationCan we remove this rule in master branch ?

It has been two years since #8637 (when using let/const lost performance), and let/const performance in V8 was improved due to #8637 (comment) and #9729 (comment)
I think maybe it's time to remove this rule now ?

That rule was instituted because using let with a for loop that way could be drastically slower than using var. The problem was fixed in V8 6.0.
This performance problem still exists in Node.js 6.x (which ships with V8 5.1). Since code that lands on the master branch can be backported to 6.x, the rule remains in place. Support for 6.x ends this June, so starting in July, we can disable the rule. At that time, the oldest supported Node.js version will be 8.x, which currently ships with V8 6.2.

Or start a pr and add the label don't land on 6.x ?

6.x is in maintenance. I think we can already disable the rule.
