Hadn't heard about that before, looks interesting. But AFAICS mise focuses on installing tools, not actually all dependencies. It integrates with the languages dependency management tools, which doesn't help you if the language doesn't even have one or the integration wasn't written yet.
I'd rather see more adoption of guix for this purpose. It is a single package manager with a functional approach that allows for introspection of all dependencies (down to the bootstrap toolchains used to build the bootstrap toolchains that build your toolchains, which is something that AFAIK no other package manager except for nix can do), has a fairly large package repository, straightforward locking, actually tested packages, and very easy build recipes (unlike conda-forge...).
