I admit I haven't used Python that much, but I'd say about 90% of the libraries and projects I had interest in didn't have a requirements.txt. I've used Node a LOT, and I have yet to have a library or project -not- have a package.json. I'll readily admit that Python has the -ability- to be a well maintained environment. THe fact it doesn't default and practically enforce it has led to a culture where it's not often used. And half the mindshare uses conda environments instead.
