There's a built-in feature that Perl has that only a few of the languages claiming PCRE have actually done, and it makes things a lot more readable. The
/xmodifier lets you put in whitespace and comments. That alone helps a lot if you stick to good indentation practices.If all other code was written like an obfuscated C contest, it would be horrible. For some reason, we put up with this on regex, and we don't have to.

I agree, but then there's also some other niceties that come from expression parsers in the language itself (as noted in the article): syntax highlighting, LSP, a more complete AST for editors like helix.
Syntax highlighting works fine as long as your language has a way to distinguish regexes from common strings. Another place where Perl did it right decades ago and the industry ignored it.
Nah, the language itself should be as simple as possible. Bloating it with endless extensibility and features is exactly what makes Perl a write-only language in many cases and why it is becoming less and less relevant with time.
Except it has some really good ideas that should be copied. There are other languages that have a syntax for denoting regex, such as
~r'foo'in Elixir. This gets the syntax highlighting you need without a big addition to the language.
