Examining http://radioscanningtw.jidanni.org/index.php?title=Special:Deadendpages&uselang=en we see The following pages do not link to other pages in this wiki. Showing below up to 50 results starting with #1. View (previous 50) (next 50) (20 | 50 | 100 | 250 | 500). Why can't the big secret that there is a total count of 235 be revealed somewhere in the wording without requiring the user to go clicking around to find out?! I'm not saying show them all, just divulge the total number. Same for similar Specialpages.
The simple explanation is that, in quite a few of those cases, finding out that information is too expensive to be worth it.
Hurmf, getting a little COUNT(VARIABLE) more expensive than SELECT(...) LIMIT 50, or however you write it? Well at least it's many bytes less. But you are the pros...
Will not implement this since COUNT(xx) is too costly in most cases.
