I don't think it is too late at all. I have had some set-backs 
w.r.t. porting d-runtime, but there is nothing technical prevent 
completion.

I have D running on cloudflare's edge network. They start up the 
module on each request (in less than 1 ms), beating any 
container/lambda thing I have seen.

You can easily creating bindings to wasm3, or wasmer, or 
wasmtime, or any of the others, and host wasm code.

Or use them to run your D code on a large variety of platforms, 
see https://github.com/wasm3/wasm3#status for a small list.

The cool part is that other people are figuring out compatibility 
between all the languages that compile to wasm, and we just 
piggyback on that because of LDC.
