I still think a lot depends on whether you view it as a dropper post, or an upper post.
I you’re the kind of person who rides a lot of flowing XC for miles and miles then you use it as a dropper, only dropping for the techy descents, chances are you feel like you could probably do without one.
If your riding is more winch and plummet and a lot of techy riding then you probably treat it as an upper post, default down and raise for the climbs and longer peddally bits, chances are you might also be happy to stop to adjust and can do without one.
It’s the middle ground all round riding where i now wouldn’t be without one.
If you do a bit of both then You probably end up in the same camp I’m in, some of my bikes have them, others don’t, the ones that do I would miss the dropper on, and the ones that dont I never feel like I need it, so yeah, as much about the bike and the kind of riding you do as anything, and the more genuinely all-round your riding and trails are the more useful one becomes as you end up in that sweet spot where you needs and upper and a dropper a lot on the same ride 🙂
