I think the ideal is that a task has finite work and is eventually closed.
Yes, this is the reason some dislike the tracking tasks; not a problem if you create reports for, say, 12 different classes of actionable search problems and add a handful blockers for each.
(A contributing factor was that Phabricator's support for dependencies between tasks is awful: hard to add, no flexibility in notifications, no charts, no searchability. Tracking tasks were very powerful in bugzilla, not so much in Phabricator.)
