Provided that the future plans for new syntax don't involve breaking 
lots of existing code, then I would say yes. I'm not yet convinced that 
this is true for the future RAII syntax (but I'm not convinced that it 
isn't true, either).

It's a lot more than that. It means "this release is officially blessed 
for building libraries". Right now there are libraries which only work 
for (say) DMD 0.153 - 0.162, and others which only work for 0.148-0.155.
1.0 is an announcement that all existing libraries need to be updated, 
and that in the future, they won't be built against completely arbitrary 
versions.
