A portable, modern regular expression language
I had a similar kind of idea for a long time, which I put into action a few weeks ago via a standalone transpiler of Emacs' rx macro to common regexp syntaxes.[0] I ended up getting interrupted and didn't completely finish it, but it generally works, though is probably riddled with edge cases.
The basic idea of rx is to use S-expressions to describe regular expressions, and my elevator pitch would've been to embed rx invocations in shell scripts using $(syntax), the main use case being something like sed invocations.
I still think it's a neat idea, and complex regular expressions tend to be hard to parse for humans.

I find something like this a lot more readable:

It is in Julia, but if you have it installed locally it’s just a few taps away. You can even generate the regex, and use that in Python and just add the ReadableRegex in a comment nearby.
