For example, this could be an issue for generic functions:

Not really.

    const T value = arr[0];

means that value isn't going to be subsequently reassigned or anything mutated 
through it.

Also, you forgot a fifth case where only part of the type is const/immutable:

5. const(T)[] x = ...

The default const'ness would apply to the [] part.
