> So in D, is it now natural to mix borrow checking and garbage collection?

I think "natural" is a bit loaded, there is native support in the frontend for doing both. You have to go out of your way to annotate functions with @live and it is still experimental(https://dlang.org/spec/ob.html). The garbage collection is natural and happens if you do nothing, but you can turn it off with proper annotations like @nogc(https://dlang.org/spec/function.html#nogc-functions) or using betterC(https://dlang.org/spec/betterc.html). There is also @safe, @system and @trusted(https://dlang.org/spec/memory-safe-d.html).

So natural is a stretch at the moment, but you can use all kinds of different techniques, what is needed is more community and library standardization around some solutions.
