Depends entirely on you use case and how you ski.
Do you hike a good bit of terrain? Spend a good bit of time walking to/from parking or around base area? Have to deal with kids? Work on patrol? Coach a ski team?
If you're ripping GS arcs all day and don't shuffle around much -- probably overkill. But there is a reason I see lots of patrollers and race coaches these days wearing boots like the Lange XT Freetour, the Cochise, Dabello Lupos, etc.
I wouldn't prioritize it in a boot over other characteristics unless you have good reason to. But I find mine very handy to have and it will be a feature of my next boot.
(Yes, you give up a tiny bit of performance. My skiing isn't so perfect that those 2% matter, maybe yours is. Yes some of the older mechanisms suck -- but most modern mechanisms are really dialed.)
