I left a comment linking to the G-code list on the site for Marlin firmware as a further resource.
The author, a moderator, responded:
It would be better to point people to the RepRap G-code reference, this site is not firmware specific but targets more firmware flavors.
But that confused me. I don't see any meta question outlining a 3DPSE policy that it is not firmware specific.
I thought answers should be as relevant to the question as possible on the stack exchange network. The OP of the question flagged it for a Creality Ender 3, which uses Marlin, so why is it not better to refer to a Marlin site?
After all, RepRap, while it does use the same G-code as Marlin, is a specific firmware. If we do have a policy of always linking to neutral G-code references, wouldn't it be better to link to something like the Wikipedia entry for G-code?
So I'm looking for clarification on site policy/best practices.
