Just in case anyone revisits this via a search.
Scoop does handle multiple versions quite nicely (see FAQ · ScoopInstaller/Scoop Wiki · GitHub). Whoever looks after the scoop elixir & erlang manifests is doing a great job of keeping it up to date.
The major limitation compared to asdf is that scoop doesn’t handle per-project version configuration, so you have to scoop reset [app]@[version] to switch the version globally.
