1 person's needlessly at risk is another persons essential work. UK members of Parliament are very active in their local community, their parliamentary email address is the normal one to be using for this type of work and may involve needing to sign up for things with an email address. When they are following best practices and using a unique password then they aren't really putting anyone's information at risk. They are at risk from phishing attacks simply by having such an email address which is publicly available, but that is an accepted and managed risk and definitely not needless.
