Mayweather always suspected that boomers were more affected than anyone else by lost colonies, since those colonists also had chosen to live a life outside Earth. (ENT: "Terra Nova")
Brannon Braga once characterized the concept of boomers as "an interesting idea" but remarked, "It was badly executed." ("To Boldly Go: Launching Enterprise, Part III: First Flight", ENT Season 1 Blu-ray special features)
In the writers' second draft script of "Breaking the Ice", Archer asked Vulcan Captain Vanik if he had actually never previously encountered a boomer ship, to which Vanik implied that was correct. In the final version of "Breaking the Ice", the possibility of a boomer vehicle having been encountered by Vanik is ruled out by T'Pol simply commenting, aboard Enterprise, "I believe this is Captain Vanik's first visit aboard an Earth vessel."
In an ultimately unused line of dialogue from the first draft script of "Fortunate Son", Trip Tucker responded to Travis Mayweather, who had explained that boomer culture allowed for lots of time for procreation between ports, by remarking, "Sounds like there's some definite advantages to being a Space Boomer."
