I've proposed it in the past, but Walter had been against it.

Compile-time GC had broke some pull requests, at least including mine.

And, as far as I know, it had increased compilation time.

Adding gc in Windows:

Removing gc:
https://github.com/D-Programming-Language/dmd/commit/8515995

I couldn't find the commit for stopping gc use...
