Heard that many on the Frontier team hated Someguy's mods as they were "triggering" and "offensive". At least with Someguy's mods he was inspired by western movies made by Sergio Leone, Sergio Corbucci and Sam Peckinpah and books written by Cormac McCarthy (NVB1 and Russell was inspired a lot by Blood Meridian), Larry McMurtry (The character of Red Bear was inspired by Blue Duck in Lonesome Dove), Louis L'Amour, Elmore Leonard and Elmer Kelton. Since New Vegas is at it's core a western many of those themes fit well with New Vegas and can be considered lore friendly.
With the Frontier there was nothing lore friendly about this mod. The progressive Legion was, perhaps, one of the most insulting lore breaks I saw. The fact that they tried to make the Legion "progressive" and conform to current year gender politics shows that not only did they not understand New Vegas but also couldn't separate art from the artist. Also, the devs political views and logic are quite strange to me. The Enclave are evil, racist, fascist, Trump supporters but the Legion are fine as they have strong women in their ranks now so that makes them progressive. Just because you have women now engaging in the horrible war crimes that the Legion commits doesn't make them progressive. True progress would be the Legion not doing things like slavery or crucifixion anymore. This is the type of political outlook and logic I would except from a Twitter gremlin.
