Why would it? init is the state of the object before any constructor runs,
and quite a few things rely on it. The fact that we've allowed default
initialization to be disabled already causes plenty of problems as it is.
It's occasionally useful, but it definitely complicates things. D was
designed with the idea that every type has an init value.

What problem are you trying to solve here?
