I don't really see any difference in intent between these fan films and the novels that have been written about the TOS period. People want more and have almost since the series ended. If fans were able to do these sorts of films in the 1970's you can bet that they would have. I see it as just a desire to continue on with something that the people love. Let's face it; we've seen the original episodes so many times and still love them but it's cool to see something fresh, IMO.
