Wine for Amiga is as confusing as Windows Subsystem for Linux. I thought it would be a port of Wine for the Amiga but it's instead something to run Amiga software on PC.

vAmos is just CPU and an embedded ROM/OS replacement that does just enough to run (some) AmigaOS command line programs. The primary use case is for cross-development (running Amiga compilers/tools, testing simple stuff, etc.) without having to boot a full system emulator for each command and better integration with e.g. host-side Makefiles.
With the vAmos=WINE analogy, Amiga Forever=VirtualBox/VMWare.
