Better gamify the UX for snowflake extension

How do we make sure that users don't uninstall the extension if it seems like it isn't being used?

Sometimes usage is low due to bugs but other times it could be due to very few clients using the system. Is there a way to reassure people that the extension is still working or will be useful in the future?
