Thanks for writing this, some very good points here. I think that 
making migration easier is something we need to focus on, but 
that probably needs dmd as a library to be easier to use.

In the case of DIP1000 specifically I think maybe Robert's idea 
of moving its checks to `@trusted` may be that way forward, and 
making `@safe` regular GC D. Once I'm done with editions I'm 
going to write a DIP for this.
