Spawnfest/bakeware: Compile Elixir applications into a single executable binary

From the repo:

Creating cross-platform binaries

Bakeware binaries include the Erlang runtime but there are still dependencies on the host system. These include the C runtime and other libraries referenced by the Erlang runtime and any NIFs and ports in your application. Luckily, the binary ABIs of many libraries are very stable, but if distributing to a wide audience, it’s useful to build on a system with older library versions. Python has a useful pointers in their packaging guides.

If I am understanding correctly this doesn’t solve completely the issue of compiling for cross-platform as it’s solved in Rust or Go. Am I am missing something?
