I think it would be better to have a single PR that include #31049 and #31051. Having lots of very tiny PRs is a lot of overhead in this case.

I am not sure we should really change these as long as we do not touch any of these files due to something else though.

@cjihrig had raised similar request, and this is explanation I'd given #30962 (comment)

A single PR will need lot of follow-up, when different decisions are taken for different submodules like:

• buffer changes are not accepted buffer: use for...of #30962
• http changes are not accepted for headers http: use for...of  #30958
• stream changes won't land on 10.x stream: use for...of #30960

Closing as most collaborators are opposed to such changes.
