It's cheap for a single bool, granted, but consider arrays of bools:
bool[large_num] array = void;
Void init is primarily a thing for static arrays. Silently initializing those
with zeros is basically (performance) code breaking. Note that someone with
writing that code with reasons did that for performance, so it *is* a breaking
change.
