Mostly by reusing existing version managers, which have been developed and optimised over the years. Asdf itself is a relatively thin wrapper really.
The only exception I can think of is any dependencies on libraries that may or may not be installed by the system package manager. Even then, those dependencies are often optional.
The low barrier to entry is also a bit of a curse too. The quality of asdf tool scripts varies wildly. Anything not maintained by their core org is a crapshoot in my experience. Many of those smaller tools don't support ARM or have lots of undocumented dependencies or quirks.
