Compiler toolchains are hardly compromises needed to compile code on a PDP-11.

I do agree that UNIX compilation model is not the best example around, though.

Nonetheless, most languages on UNIX like OSes will for the most part follow the same model, as they need to fit into the ecosystem, as otherwise there is always an impedance mismatch that will prevent their adoption in some cases.

That is how you get modern languages like any wanabee C or C++ replacement using the same compiler toolchains and linkers, instead of compiler based build and linker systems, as languages not born into the UNIX culture.

Thus pretending systems programming languages are like scripting languages will hardly help.
