(Is it usually drop-in compatible?) Unfortunately I don't use Matlab and don't have a license to try out. However, as I understand Octave's mex interface, the original goal was to allow Matlab extensions to be compiled and run in Octave. Otherwise you could have a core language that ran Matlab code but extensions would still lock you in to Matlab. Thus, I'm assuming that the ability to use Octave's mex interface implies ability to use Matlab's.

[...] D is a much more capable programming language than C, and whatever functionality is being imported from the C standard library can be better implemented in D with compile-time optimizations via templates, memory safety, and other benefits. So if I understood correctly, you did not mean ejecting core.stdc but that DRuntime should not depend on it? Yeah, that sound reasonable for me too (If it is practical effort), regardless of DPP. But C libraries should be kept as a backup for platforms where there aren't D implementations. For example, IO functions could first try (using design by introspection) some implementation like https://github.com/schveiguy/iopipe. And if that does not support the enviroment, then fallback to C IO.

There are druntime implementations that leverage the C standard library, but I believe that was largely done for expediency. If one wants to leverage the C standard library for a certain druntime implementation, that's fine, but it should be privately imported. D is a much more capable programming language than C, and whatever functionality is being imported from the C standard library can be better implemented in D with compile-time optimizations via templates, memory safety, and other benefits.

As I understand it, they do not increase your executable size unless used. Besides, the bindings include the @trusted and scope attributes C++ headers don't, and are quicker to compile.

It might make sense to split those bindings off into their own git repo, separate from the compiled parts of druntime though.
