Following the directions at https://www.mediawiki.org/wiki/Manual:Pywikibot/login.py https://www.mediawiki.org/wiki/Manual:Pywikibot/login.py, when I go to https://meta.wikimedia.org/wiki/Special:OAuthConsumerRegistration/propose https://meta.wikimedia.org/wiki/Special:OAuthConsumerRegistration/propose, I'm being asked if I want a 1.0a consumer or a 2.0 client. Which do I want for use with pywikibot?
