Your @legacy is really no different than putting @trusted: at the 
top. I agree with others who are concerned about marking all 
current code as @trusted, rather than @system.

To your other point about it being ugly to mark main as @system, 
I recall Walter considering, at some point, keeping main as 
@system. Perhaps give main more time before changing the default 
to @safe?
