This would also be useful for the average end user. Even some sort of automated smoke test (Even if its just add extension to LocalSettings.php and if its a parser tag maybe test parsing one page with the tag on) just to make sure mediawiki doesn't fail in a ball of exceptions/fatal errors) would be helpful to end user if results were posted to the extensions page.

Noticing an extension doesn't even remotely work on current mediawiki is also a good metric for if its abandoned (albeit with lots of false negatives)
