We can merge the whole stack, with uncertainties in a separate issue.

I've fixed the down stack formatting issue, About the uncertainties; Are you talking about the conversations I've opened here #3954, If that's the case I have to say I agree.
The actual generated code - you can say the majority of the changes - would be unaffected and if we want to change anything it would be in the codegen + some attribute changes in the AST(which is limited to a few lines).
