nor is it an appropriate greeting for every newcomer.

I don't even warn every newcomer who mentions the QM sequence, let alone "every newcomer"

My standard advice to all newcomers is to skip the quantum sequence, at least on the first reading.

It is rather disingenuous to then express exaggerated 'let alone' rejections of the reply "nor is it an appropriate greeting for every newcomer".
