I use mine on an Enduro bike, ride it for just about everything including trails. As it doesn’t have a platform switch, some bikes and riders might struggle with it depending on their riding style (ie standing up mashing pedals on climbs rather than seated winching) and how the bike’s kinematics are too.
So it’s not so much about being “not trail friendly” as being focused more at the gravity end, with a big damper, not light weight and no platform. But it’s very much horses for courses.
I’d definitely say it’s worth seeing Jake at Sprung in the FoD as he can do setup days, video analysis etc and from there make recommendations as to what will work best for you 🙂
