Sorry, due to fumblefingers I gave the wrong URL for [1]. Here's a 
corrected URL:

https://github.com/PCRE2Project/pcre2/commit/8385df8c97b6f8069a48e600c7e4e94cc3e3ebd9

It also mentions a new --case-restrict option, intended for 10.43 
pcre2grep. Given Perl's and PCRE2's plethora of options I suppose one 
could imagine several other options of that ilk.
