I request the developers to add support to https://www.mediawiki.org/wiki/Extension:SecurePoll extension. This is a higher-level extension which very few people have access to on Wikimedia Wikis, hence will be useful for testing.
Rights of securepoll-create-poll and securepoll-edit-poll can be granted to sysops/'crats based on consensus, or even as a separate electionadmin group which can be added by sysops/'crats.
securepoll-view-voter-pii needs to be limited to CheckUsers as it shows IPs.
Thanks!
