In Python 3.6, the keyfile, certfile and check_hostname parameters were deprecated in ftplib, http.client, imaplib, poplib, and smtplib modules. IMO it's now time to remove them in favor of the context parameters. Most Python projects now require Python 3.6 and newer (if not Python 3.7 or Python 3.8). And it's easy to support older Python versions with some if/else code.

I wrote PR #94173 to remove these parameters.
