This is true for all of the callsites that I've seen, but I think I remember
talking to someone who said the intent was that you might also use this to
analyze the initializer of a global variable (where `D` would be the variable
declaration and `S` would be the initializer). It seems telling, at least, that
the interface expects only a `Decl`, not a `FunctionDecl`.
So I'm hesitant to remove this API entirely without more investigation. It
certainly makes sense though to add an overload that takes a `FunctionDecl` and
no `Stmt`, which will cover the vast majority of use cases. I'd like to do that
in a separate patch though.

Thanks for pointing this out! Done.
