Even if escaping references to the stack are rare, it is very very important to 
catch them as they are hard to track down and cause silent data corruption. 
They're some of the worst bugs.

@safe recently found a data corruption bug in the druntime stack unwinder that 
had been there, latent, for years. (It hadn't caught the bug before because I 
had overlooked checking the msg argument to assert() for @safe errors.)
