I did read they were interchangeable, "for" and "of". But what about using them with words that typically use one or the other?
to instill respect for and knowledge of our policies
to instill respect and knowledge of our policies
Are they both valid sentences (fragments)? To me the latter sounds like I'm saying to just "instill respect" with no reference to the subject (policies) or "instill respect of our policies" which may or may not make sense
