Yep, totally my point, besides that being apparently no big deal (let alone
critical issue rendering a compiler 'totally broken') for the comparatively
huge Visual C++, Rust and MinGW user base. And with an absolutely trivial
solution - just install Visual Studio and use the static libs (I think that's
the default setting for DMD too, for LDC it definitely is), then your users
won't need the redistributable.
And that seems to be the crux - some Windows guys seem totally opposed to the
idea of having to install the 'official system toolchain' for professional
development, while having to install Xcode on Mac (also required for linking in
general, not just to have the ability of linking the C runtime statically) is
somehow far less considered a PITA.

That'd be too late; druntime's _d_run_main (IIRC) is called from C main
(emitted by the compiler), which is called by the C runtime, as that's where
the actual entry point is.
I wish Microsoft had added something similar as convenience ages ago - if the
binary requires one of their runtime DLLs, offer the option to download &
install it automatically for them, but they apparently don't find it that
critical or rather shift the burden to the software packagers.
