Owners of a rule must currently be an individual account within Jira, and can be notified if rules are failing. However, my team are the true owners of these rules, not just me as an individual — any team member of mine should be notified that things are failing and can take appropriate action.
To that end, please allow one of the following:
The ability to set a Jira group as the owner of a rule, or
The ability to set multiple Jira users as the owners of a rule, or
The ability to set "project administrators" as someone who'll be notified of failure, or
The ability to set emails as notification targets — perhaps maybe only claimed domains in cloud to cut down on email spam, think of the Enterprise™ — or
Something else you can think of that would allow multiple users to be notified of rule failures.
