Possibly.

I know what argument is coming next: "But if the function you call 
stores the string you passed in then it can't rely on seeing a 
consistent value!"

I know this. These functions should request immutable(char)[] because 
that's what they need. Functions that don't store the string should use 
const(char)[].

The question is whether string should alias immutable(char)[] or 
const(char)[]. In my experience (which is echoed in Phobos) is that 
const(char)[] is used much more often than immutable(char)[], so it 
should alias const(char)[].
