If I have a complex regular expression to code into my app, I write it in pomsky, then copy paste the compiled regex to my source file, but also keep the pomsky source nearby. Much more maintainable.

Because not all parts of the repo have this status. Some are stable, well tested and critical.

No it is not. It depends on the codebase - if it is something relatively new, a proof of concept or something that is bound to change soon, there is no point in slowing the development down just because it is “too large to digest”.
