Yes, it seems to exist in 3.15p. Under Debian gnat 3.15p (gnatgcc 
2.8.1), this package declaration compiles without error messages:

    generic
       type N is (<>);
    package U is
       type Count is new N range 0 .. N'Last;
    end U;

Compiling an instantiation "is new U (N => Boolean)" gives error 
messages:

m.adb:6:04: instantiation error at u.ads:4
m.adb:6:04: expected type "Standard.Boolean"
m.adb:6:04: instantiation error at u.ads:4
m.adb:6:04: found type universal integer

So at least the error is detected before run-time.
