Or instead, move to SEMVER? Same effect.
Although, now might be a good time to think about D3. After all, we are 
having a massive change in the ecosystem. It wouldn't be that strange to 
think of it as more of a push for polishing.

As a library perhaps?

Can the plan include stripping out unneeded ones? And even inlining some?

Less memory = win! E.g. can we compile + run phobos test suite in < 1gb 
memory?
Because it's a real pain finding single board computers that support 
more then 1gb.

Ooo, yes please.
Perhaps even as a library?

I would love to see dmd literally along with it's backends as dub 
packages. That would be *high pitched* awesome.
