I don't think anyone uses the former expression anymore. It's unclear.

Just make all interface variables implicitly typed Object as well. Or 
make an IObject interface that Object and all interfaces inherit from, 
then make delete take an IObject as well.

Then you can have IUnknown not inherit from IObject if you want.

This is indeed annoying. IFTI gets you static array types unless you use 
[], and there was that old issue with arrays and associative arrays (and 
it still exists if you use auto).
