eh they're really in the same boat. Declaring your own WinMain is kinda

No, it's not.
For C:
Implementing WinMain does not bypass the runtime[1]. Implementing _start
on Linux would most likely bypass the runtime. Implementing WinMain is
more like implementing main() on Posix.
For D:
Implementing WinMain or main() as extern (C) will bypass the D runtime,
it still won't bypass the C runtime.
I would expect the boot process be something like this:
Linux:
_start
C main
D main
Windows:
CRT (C runtime library)
C main or WinMain
D main
Both the C and the D runtimes implement their own entry point which
calls into your program's main and you can use these consistently across
platforms.
WinMain is not the entry point. The C runtime library will call it just
like it will call C main.
