Adding -transition=? to the dmd (v2.078.0) command line doesn't 
show safe listed.
My understanding is, currently read DIP1000 as:
"NB: this DIP is out of sync with -dip1000 compiler switch 
implementation ...".

Yes, the representation of DIP1000.md deserves improvement: It 
takes (too) much time to get a grip on it, maybe discouraging, 
though the idea itself is not that complicated as it is 
presented. I additionally warmly recommend Walter Bright's
