Again, this has nothing to do with dub. It's the behavior of the 
linkers. When you use WinMain, the MS Linker will give you a 
windows subsystem by default. When you use main, it will give you 
a console subsystem.

DMD gained the -m32mscoff a good while ago in order to enable 
coff output and compatibility with the MS linker in 32-bit mode. 
Built-in dub support came much later with x86_mscoff. *That* 
needs to be documented in the dub docs, but the behavior of the 
various linkers out there is beyond the scope of dub's 
documentation. Instead, it belongs in the DMD windows 
documentation. It's currently missing:
