Would it be possible to distinguish between unknown and deprecated parameters? It would be useful sometimes to track deprecated parameters in a different category, or with a different preview message. — Martin (MSGJ · talk) 20:17, 4 December 2023 (UTC)[reply]

If there is an error category for unknown parameters then it's only added in the rendered page, not previews which instead show a preview warning. That can be very confusing. Consider for example Copa Libertadores Femenina (permanent link) with Category:Pages using flagicon template with unknown parameters. The page has 135 {{flagicon}}. The unknown parameter is in {{flagicon|BRA|side=30px}} (should have said size). It's common to track down where a category is added by previewing different parts of the code. That fails here when the category is never added in preview. You can search for the preview warning in the preview but users may not know that. Previews can add things but shouldn't remove things.
