Any drawback? They say less control and a "wobbly" feeling...Well I do frequently. I have it and I use when my wife isn’t, just makes the ride even softer. There are no rules.
I haven’t noticed any ill effects I’m not an expert so who knows. My full suspension fat bike is something I just ride dirt roads with and some trails not much pavement and when I use the (post) I only notice a different soft while handling perfectly.Any drawback?

Why a dropper would help?No need (it's a general truth: No one installs suspension seat post on any full suspension bike). Dropper post would be more appropriate if you are seeking comfort.
Not just comfort, but handling. A hardtail doesn't keep both wheels in contact with the ground as well as a full-suspension bike. This matters mostly off-road, though.I find a suspension post a poor substitute for a dual suspension bike. Limited travel and limited adjustability are it's downfall. Take Stephan Mikes opinion. I ride a trekking bike with a suspension seat post, and have a full suspension Haibike. Absolutely no comparison for the ride between the two. Taking the trekking on a single track would be suicide to my back. Taking the full suspension means comfort.
That is of course the primary use of the dropper seatpost off-road. Steep descents are done with the seat dropped, standing on pedals, with the backside well above rear wheel to move the centre of gravity backwards.And to add to this, it allows you to lower your seat on the fly, getting a lower centre of gravity for steep hills, on or off road.
Just put one of these on it!https://byschulz.com/product/d-2-st-ri-dropper-parallelogram-seatpost/?lang=en
byschulz is by the way the gold standard used for suspension seat post's amongst the R&M users on the German pedelec forums.
