“prompting update of 30+ packages” is not good.
Still I see no real reason (but may miss some aspect) not to upgrade to SailfishOS 2.2.1. Why do you prefer SailfishOS 2.2.0?
Presumably using SailfishOS 2.2.1 is the easiest way out (not only for Storeman’s use of OpenRepos, but also for many other internet services and websites), other ways require some slightly advanced use of zypper or pkcon.
