Here's a fourth, the wiki login form. You can [Log in], but you can also create an account (usually phrased as [Join <wikiname>]). They're both significant actions, so neutral for the second button doesn't quite work. So they take different colors, and over time a consistent color choice here and elsewhere should suggest the interaction distinction in the guideline, even though only a tiny fraction of users will ever be able to articulate it. The onus is on anyone who wants to eliminate it to prove it's harmful.

I just noticed the [Join Wikimedia button] is taller than [Log in], a regression. I filed https://phabricator.wikimedia.org/T116427

(I was present when Munaf Assaf and Steven Walling et al. came up with the new login, the first case for Agora, now MediaWiki UI. Good times.)
