Do you want to submit a PR?

I'd like to make it later. But if someone else is also eager to make, it is fine.

Sure, I didn't want to take credit for your research without your approval.

URL class implement is added in v7.0.0 and v6.13.0, via #7448

IIUC that's already documented:

node/doc/api/url.md

Lines 107 to 112 in 5a775b3

	### Class: `URL`
	<!-- YAML
	added:
	- v7.0.0
	- v6.13.0

URL.prototype.toJSON() implement is added in v7.7.0, via #11236

Good catch, we can also add that it was backported to 6.13.0. I can open a PR for that. EDIT: that's #55818

URLSearchParams class implement is added in v7.0.0 and v6.13.0, as an internal instance, via #7448,
and exported in v7.5.0 via #10801

It also landed on 6.x thanks to #17365, so I think the documentation is correct

node/doc/api/url.md
