Hello, I was a little confused on your reasoning for deleting WIKIDIFF ("who types in all caps? redirect should really be lower case; if there's another page then it's a redirect") and interpreted it as meaning that MediaWiki doesn't utilize the shortcut standard styling of ALL CAPS. Just noting for myself in future that shortcuts on MW do follow that style for the most part.
Topic on User talk:Clump/Flow
(I mistyped (mis-wrote) a word in that in that comment, I meant to write disambiguation.) Some redirects, older ones in particular, are in all caps but most redirects are not. Given the main use-case of a redirect being a shorter or variant name of something someone might actually type out, all caps doesn't really make much sense, at least beyond acronyms and acronym-like contractions.
That list seems to cap out at 5000 for me, and all start with $ with the exception of the last 100 or so (4917+)? However I'm using it can't be right, as for example, DYK is nowhere to be found.
Yes, there's that many, so 5K only barely reaches things starting with A.
How are you able to determine 'most' redirects are not? (Is there policy on this? Closest I can find is enwiki's.)
Out of the 5K shown only a few are in all caps. Wikipedia's compact/acronym-ish shortcut strategy is useful there, but as you may note from the dramatically smaller list of shortcut transclusions (most of which are translations too) that approach is not really used here.
I think its fair to say that wg vars (i.e., ~4915 of them) are not really what we are talking about.
Extracting the full list to more formally verify or disprove my majority claim would be mildly interesting, but is more work than I care to do, and kind of drifting off-topic. "Shortcuts"(tm) are only barely used here though, and as you already observed, are not uniformly all caps.
(I have no idea how to get that red link to work??)
Flow has a known bug that redlinks point to the wrong page. One of many reasons that discussion system is on track to be sunset soon.
