(Before using this for real, I'd certainly want to be able to track the exact version I'm getting of a dependency, with a hash, in a "lockfile" sort of file that I can keep in version control. That's not mentioned in the demo on the front page - but if it doesn't already have that feature, I hope it will grow it.)
As mentioned elsewhere, Dhall has a similar import-from-URL feature (with cryptographic hashes), and it is/was popular to use IPFS URLs, since they're content-addressed (i.e. changing the content will change the address, so each address will always point to the same data)
I'm thinking especially of the use case of sharing for people who have not been accumulating dotfiles forever and haven't set up some kind of way to manage their dotfiles in version control. (Heck, I don't myself have a system that I love for that, though it meets my basic requirements in that I can always ask Git exactly what changed.)
So "add this one line to get my prompt" is then a much lower-friction suggestion than "copy this whole little script".
