           Summary: RTInfo generation on deprecated struct causes
                    deprecation message
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal

Change the RTInfo declaration in object.di and object_.d to

////////////////////////////////////////////////////////
template RTInfo(T)
{
    enum RTInfo = cast(void*)RTInfoImpl!T;
}
template RTInfoImpl(T)
{
    enum RTInfoImpl = &RTInfoImpl2!T;
}

template RTInfoImpl2(T)
{
    immutable RTInfoImpl2 = 1234;
}
////////////////////////////////////////////////////////

and then compile a predrecated class or struct:

/////////////////////////////////////
module test;

deprecated class Dep { }
/////////////////////////////////////

emits

Deprecation: class test.Dep is deprecated

As long as Dep is not actually used, the compiler should not emit a message.
