Also I don't necessarily want to close it, I only mentioned it because apparently that was what we were supposed to do 8 years ago. If the answer is just leave it open and let users be confused if they don't happen to see my comment then so be it.

Any question on the site could become outdated at any minute, that's the nature of computing. "Too localized" isn't a proper close response for this, or I could close half the questions on the site on that basis.

The question involved workarounds for limitations in old versons of Chrome OS. It's confusing to users of modern versions but could be possibly relevant to someone with an old, unsupported device. But Chrome OS isn't versoned like say Mac or Windows, so you can't tag it like you could [windows-95].

BTW, one of the linked questions focuses on hardware shopping questions, for which we have a different close reason now. My question was prompted by a software question, though.
