https://searchfox.org/comm-central/search?q=.firstChild.nextSibling&case=false®exp=false&path= 584 hits, so you can't really say that it's badly readable. https://searchfox.org/comm-central/search?q=.children%5B1%5D&case=false®exp=false&path= 130 hits, mostly in 3rd party code, tests and devtools. Also, I have the impression that `children` is also used for style retrievals. .children and .childNodes are different, the former doesn't return text or comment nodes. Is that desired?
