As for the technology such as Transwarp Beaming: I reckon it's still experimental, as previously mentioned. There might be limits on it and certain circumstances it can or cannot be used under. Not to mention that someone like Admiral Marcus would definitely want to maintain an "upper hand" by keeping such a technology to a certain section of Starfleet (i.e. Section 31). He would want an "ace in the hole" should a situation arise, and not want that "ace" to be taken and used by someone else, seeing that he has the attitude that he alone knows how to properly use that tech. He demonstrated this attitude with the Vengeance, having had it built in secret rather than trying to justify it before the Federation Council. Such a personality has an element of arrogance and elitism that thinks they are the only ones capable of controlling a situation, possession or anything else. In fact, it's this attitude that created the conditions for someone like Khan to escape and wreak mass chaos.
