"Reviewed pages" may already be removed from the default. I cleared my cookies and my local storage, and this setting was not checked. If you can confirm, feel free to rename the ticket.

"Reviewed pages" are shown by default. Log out of wikipedia (or use a private browsing tab) and check https://en.wikipedia.org/wiki/Special:NewPagesFeed for verification.

If this doesn't work, may need to dig into the Underscore.view model at modules/ext.pageTriage.views.list/ext.pageTriage.listControlNav.js. There's a bunch of code that ferries settings back and forth between local storage, the view model, and the HTML form. Unclear where it gets its defaults from.

The default settings are in https://gerrit.wikimedia.org/r/plugins/gitiles/mediawiki/extensions/PageTriage/+/refs/heads/master/modules/ext.pageTriage.util/models/ext.pageTriage.article.js#272 with some code needed to be changed in https://gerrit.wikimedia.org/r/plugins/gitiles/mediawiki/extensions/PageTriage/+/refs/heads/master/modules/ext.pageTriage.views.list/ext.pageTriage.listControlNav.js#465

Changes look good! I opened this on an incognito browser as an anonymous user and Reviewed pages and Nominated for deletion filters are unchecked by default.
