I posted something about this over in one of the ACtA:SF threads, but I should point out that the SFU is, by the very nature of its license, not nearly as wedded to the on-screen versions of events as the Paramount/CBS Franchise is.
(To re-use an example, the Star Fleet Universe take on the unfortunate first contact between the Federation and the Gorns had "two brash young captains shoot first and face embarrassing questions later"; but states that "the event was dramatized for trivideo in a fanciful story involving an unknown super-race similar to the Organians".)
So, while the "trivideo" source material has a prominent place, it's not advisable to get too locked on to what is shown on screen it when it comes to understanding how things work here.
Star Fleet is not Starfleet.
