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

To be fair, the WebAssembly support is still WIP and hasn't even 
been released yet ;-)
Anyhow, here's how I think we can move forward for now:

1) Open the issue you experienced in the ldc issue tracker
2) Add more tests for -betterC to the test suites (and thus CI)

For (2) I have an "old" PR staling around 
(https://github.com/dlang/phobos/pull/5952), which I should try 
to rebase and get into Phobos. Then it should be easier to add 
more -betterC tests for Phobos.
