I just saw a question tagged [tag:whmcpanel] for cPanel's WebHost Manager (WHM). I vote that [tag:whmcpanel] (with 75 questions) be retagged [tag:whm] (which has 239 questions)

Arguably both could be merged into [tag:cpanel] but cpanel questions could be from users who don't have access to WHM, so I don't think that's a good plan. But [tag:whmcpanel] and [tag:whm] are redundant.
