I think a big source of problems when introducing breaking 
changes was that it wasn't really tested on any prominent 
codebases, so the only breakage index was D unit tests. As far as 
I know, DMD is tested against top N dub packages at the moment, 
so before you break something for users you can figure out how 
much of an effort it will be. There is a difference between 
breaking top packages and breaking a single package that only few 
people use.
