The question is why, I mean asdf is a little bit of a hassle to set the first time, since all the versions of OTP you install are compiled on your device, however once you install all the dependencies it works like a charm.
The environment setup is a thing that I love about asdf, simple and declarative: use global versions for all projects and local for the projects with .tools-versions defined. You will never use a different version locally to develop on a released product, even if you have to you can just modify/delete .tools-versions locally.
The last thing that I don’t see is the possibility to define the OTP version, this is one of the most important features of the version tool, moreover the elixir should be compiled with that specific OTP version to ensure that all the features work correctly.
