Any alien sighted must be assumed hostile

 Under any assumed Prime Directive its discouraged for any advanced species to directly contact any other offworlder. Its neither safe nor necessary. So it follows brazen alien displays are made with malice aforethought.  Like Edolph Mollusk's plans to desecrate wilderness planets. 

Something else relating to spacefaring. This is an inalienable human/ cyborg right by birth / respawning alone.  Anyone trying to make space emigration an elitist affair is an enemy of all. Barring unforeseeable disaster most alive today should be alive a century from now onboard starships. The first three might set out before 2046 the way things are going. Priority One.

Section 1:

Starfleet crew will obey the following with any civilization that has not achieved a commensurate level of technological and/or societal development as described in Appendix 1.

a) No identification of self or mission.

b) No interference with the social, cultural, or technological development of said planet.

c) No reference to space, other worlds, or advanced civilizations.

d) The exception to this is if said society has already been exposed to the concepts listed herein. However, in that instance, section 2 applies.

Section 2:

If said species has achieved the commensurate level of technological and/or societal development as described in Appendix 1, or has been exposed to the concepts listed in section 1, no Starfleet crew person will engage with said society or species without first gathering extensive information on the specific traditions, laws, and culture of that species civilization. Then Starfleet crew will obey the following.

a) If engaged with diplomatic relations with said culture, will stay within the confines of said culture's restrictions.

b) No interference with the social development of said planet.

The Prime Directive was frequently applied to less developed planets which had not yet discovered warp travel or subspace communication technology. The second section of Prime Directive was also applied to advanced civilizations that already knew of life on other worlds but were either independent or protected by empires outside the Federation's jurisdiction. First contact could be made by the Federation with alien worlds that had either discovered warp or were on the verge of it, or with highly advanced civilizations that simply hadn't ventured into space yet. In those cases, the Prime Directive was used as a general policy to not disrupt or interfere with their culture when establishing peaceful diplomatic relations
