• https://gerrit.wikimedia.org/r/#/c/pywikibot/core/+/571001/: always use Site.userinfo in favour of Site._userinfo (@Xqt, @Dvorapa)
• https://gerrit.wikimedia.org/r/#/c/pywikibot/core/+/572484/: Use site.userinfo getter instead of site._userinfo within API (Xqt, @zhuyifei1999)

Yeah, seems not everywhere is good to replace _userinfo()

But there is also an endless loop with API login(retry=True), and another loop with site.login(). And loops mentioned in parent task.
