Wouldn't you rather they call it a silver title then an interim title? Interim titles don't make sense because they are often awarded while the real titlist is still active. At least if you have a silver champion then they are making no bones about him not being THE guy in the division.

Imagine if they had a fairly (we can only imagine lol) constructed 'silver' rating system with a mix of up and coming young fighters who aren't quite ready to contend for titles or maybe haven't earned it and a bunch of hard luck old veterans. That would be a good thing actually! So often prospects do jack shit until a sanctioning body hands them a title, what if they made them earn a silver title first and then defend it against quality opposition a certain number of times until they could get a title shot? I would be in no way opposed to this.
