Please add a new option to filter [[Special:Newpages]] by page size. Thus, pages with very small size (which should be deleted per empty or no content) and pages with very large size (possibly copyright violations) could be easily found. (Hundreds of pages are created every day in largest wikis and it is very tiring to check them all manually.)

Patch needs only minor code style changes and a commit message that explains what the patch does and does not refer to a previous versiosn of that same patch.
Akshay: Patch has been inactive for a while so I'll reset the assignee of this bug report, but please assign this bug report again to yourself if you plan to work on your patch again and fix the remaining small issues (which would be very welcome to get this bug fixed!).

I've tested this query on all shards, several wikis, with special attention to all large wikis (enwiki, dewiki, commons, wikidata, frwiki, zhwiki) both in the regular traffic slaves and special slaves. I found this query to be as good as it gets, detailed results follow (I only show the results on enwiki because the other ones match this):
