O.K., so now that I'm on a brief reprieve from dictionary-entry imports (pretty long story)...
As extension users will know/have known, DynamicPageList3's default result maximum is 500, long a disadvantage for wikis with higher page counts. In my case, the English-Tovasala entries in my site's conlang dictionary partially depend on two control lists--the General Service List (GSL) from the 1950s, and the much more recent but now-defunct Landau Universal Vocabulary (LND)--whose item count each hovers above 2,000. To make sure DPL3 more or less adequately covers all of their headwords in the long term, I propose a safety-net threshold of 2,500 results for that wiki (unless constraints, technical or otherwise, intervene). (At least now that an upgrade occurred last month...)⊙
This is only the beginning of my DPL3 wishlist; I already pointed out a smattering of other unaddressed shortcomings at MediaWiki last August. (Yes, I know the original developers have recently gone AWOL...) As an aside, I also have my next (long overdue) PageForm to see about, but that's for another filing.
As I've expressed before on MW, a handy, useful extension that deserves far more attention/promotion (absent Semantic MediaWiki, whose issues on Miraheze have been documented elsewhere).
Once again, many thanks!
