Is there any plan for a dependency-free subset of "core" runtime?

Well, since 2.079 it's actually possible to use D without a 
dependency any runtime (even libc):

https://dlang.org/changelog/2.079.0.html#minimal_runtime

Also with -betterC you can actually use lots of things from core 
that don't depend on the runtime. For example, 
std.algorithm/range works in betterC:

Now, I assume you are asking whether there are plans for a 
minimal -betterC runtime?
There aren't "official" plans, but AFAICT a few people are 
independently working on this. It might be a good idea to join 
efforts with them.
