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.
