Might be unfair to call Proton a "translation layer" because the Win32 API is not defined in terms of system calls but rather a set of functions exported from a DLL.

Proton supplies a DLL that implements the Win32 API using Linux syscalls. Windows supplies a DLL that implements that Win32 API using Windows syscalls that you're not really supposed to use directly.

Wine is translating Windows ABIs (not APIs) into underlying Linux OS and userland. Translation simply means that normally Windows ABIs are meant to be used on Windows, they aren't native on Linux.
