^Technically, that statement isn't for or against bringing back the Prime Timeline. Like a kids show referencing something that kids will understand but for adults to get.
An example (and the reason I became a brony for a bit):
Though the Big Lebowski is definitely not for kids, the adults who saw this scene got something extra from it. The kids couldn't care less about the people in the background and they're not going to stop watching it because they're there as I imagine a TNG reference in a 25th century series will be received by someone who's new to the franchise.
Yeah I used "My little pony" for an example, deal with it.
