This is the done already by reggae. Unfortunately, since every

need to be recompiled is usually large, despite the fact that
for most changes the recompilation isn't actually necessary.
Do you think it might work if it did dmd -H and make the
auto-generated .di file and then did a content-based change
detection on them for recompiling dependencies?
Probably. In fact, I had a plan to do exactly that and measure to
see what the difference was. I just haven't gotten around to
doing it yet.
It'd prolly still do more work than it has to, but seeing .d
changed, rebuild .di, if .di changed, rebuild other stuff might
just avoid full rebuilds upon just simple function body changes.
That was my idea as well.
