This is how DMD v2 was developed at the beginning, I bet the 
version 1 compiler still has the -v1 switch.

I'm with Johnathan though. I don't see much benefit. Yes, the 
system has great benefit, but we can't support it.

If we create a stable branch we'd need to define what is "big" 
and decide on a support system, what do we do when the dev branch 
has another "big" change and need to have a stable-dev... How do 
we change the "big" changed dev to stable without being 
"unstable." Eventually these happy people will get the unhappy 
news they have to fix their code and probably don't have the 
resources to keep it up for years.

Maybe someone else can take on the task of merging bug fixes into 
their branch, yes a little bit of rework for them, but will that 
matter if the fixes merge cleanly?
