You must not develop anything in Perl 5 because I can't get a single Perl 5 version after 5.26.1 to compile through perlbrew - at least one if not multiple tests fail.
I'm not saying that yours is not a valid data point, but "developing in perl" strikes me as likely to be a fairly tiny subset even of developers in general.
Fair. Catalina is the last version of macOS that I will run. I will move my mac mini to Linux after Catalina loses security support, should it live that long, or I'll replace it with a NUC running Linux if it doesnt.
