There's no NEED for behind-the-scenes anything, which is what makes it a nice gesture for them to offer it anyway in the first place.
I find myself both agreeing and disagreeing.
On one hand you're right, none of this matters or even really affects our spending habits. If we like a thing then knowing a few behind the scenes tidbits, or potentially knowing it was coming a year or two out due to tell all interviews, won't change much.
On the other hand... I find the general vibe of the present team much more agreeable than the past. Be it Archer just having a different outlook, or maybe being scared straight due to the TFW/TFormers drama, he and his team had very... I don't wanna say confrontational vibes... but very stonewall-y vibes?
You can say "oh different time and place" and you aren't wrong, but having experienced both I'd much rather have a team that will say two years out "oh we're planning this character because fans have wanted him for years and we found a slot" and "so here's a peak in how the development of this figure shaped up."
There's an openness and willingness to talk to fans on their own terms that the other team just didn't have, and I appreciate that greatly about the current team.
Because yeah, none of this is serious. Which works in the other direction too, because since it's not... the "we can't comment on that at this time" answers we used to get come off as silly in retrospect.
Fans who think they know stuff they don't, and general entitled fans, are always annoying but I'd rather not throw the baby out with the bathwater.
