Should PPCG rules or guidelines or other administrative content be considered "official" when it is not hosted on meta or main?
(Note that "PPCG" refers to the entirety of the Programming Puzzles & Code Golf Stack Exchange site microcosm, including main, meta, and chat.)
Currently, most of our specific rules reside in various meta posts while other guidelines and info are in the help center and tag wikis and such. But the mods recently created a "Chatiquette" github page for chat etiquette in our chatroom, The Nineteenth Byte. The chatroom description links to it directly:
General discussion for codegolf.stackexchange.com | Guidelines: ppcg.github.io/chatiquette
So I take it that the guidelines are more or less official, akin to a meta decision.
Should these github hosted Chatiquette rules be considered binding and official? i.e. should mods (and the community at large) be able to enforce them as they would any other site rule?
In general, should PPCG administrative content not hosted on PPCG ever be considered official?
