PageTriage makes use of a user right that toggles some features on. For example, if you're in the "New page reviewer" group on enwiki, then the Special:NewPagesFeed UI adds a "Review" button in each row, and clicking it will load the page curation toolbar.

For QA and debugging purposes, it would be nice to have a query parameter to allow for users not in that group to:

• see the "Review" button on Special:NewPagesFeed
• after clicking the "Review" button, be able to see the page curation toolbar

Actually attempting to submit a review via the toolbar would result in access denied, but that's OK. The idea is that we should be able to see and interact with most of the features in production, for QA / debugging, especially as the extension can behave differently depending on how it is configured on-wiki.
