Once the Special:NewPagesFeed rewritten in Vue replaces the old Special:NewPagesFeed, I think $wgPageTriageInfiniteScrolling and the pagetriage-more message are going to become dead code.
These did not get ported over to the new Vue Special:NewPagesFeed, and I am fine with that. Not porting these over simplifies the code, which decreases technical debt.
- wait for Vue Special:NewPagesFeed to replace the old Special:NewPagesFeed
- remove $wgPageTriageInfiniteScrolling setting everywhere it occurs
- remove pagetriage-more from i18n/en.json and i18n/qqq.json (other spots where this occurs will hopefully get deleted when we delete the old Special:NewPagesFeed, although feel free to double check)
