I expected this to take at least another year or two. I am very 
glad it is happening now.

Because of dip1000 I have been using @safe for a while and having 
it be the default is the only thing that makes sense. Mainly 
because of the fact that of all d code out there, only a small 
part is @system (and it should decline relatively going forward), 
which means that annotating the system parts is easier than 
annotating the safe parts. Especially when you have the compiler 
complain something isn't @safe versus pretending everything is 
@system.

To abuse a Chinese proverb: the best time for @safe as default 
was 20 years ago, the second best time is now.

With the preview and revert flags there is plenty time to develop 
tools to automate the transition, as others have mentioned here 
as well.
