I think where ST excels is capturing the era. They do it perfectly. As these child actors grow into their awkward years and story gets more stale, it makes me wonder if they'd consider a throwback prelude season or even a total spinoff ala Better Call Saul to the 60/70's or something.
From what I've been reading/watching they plan to ease the kids into the 90's and put that stamp on ST as well...
