Honestly, I'm here half wondering why we need the click at all. One finger drag for move, quick one finger tap for left click, tap and half for click and drag, two finger tap, two finger drag for scroll covers all the common interactions.
Which isn't to say I don't use the click functionality at all. I will subconciously use it in some scenarios, but not in others, but if it were missing I would adapt very quickly, since I use the gesture alternatives so often, that I would automatically fall back to them.
I suppose I need the click for some obscure interactions like right click drag, but honestly except in games I've almost never seen that used. My surface laptop as currently configured literally wouldn't even allow some other rare ones like hold button and scroll (I'd need to turn on right side scroll-wheel for that) and I've never even noticed the absence of that ability until I tried it just now.
The type that doesn’t move at all and simulates a click with haptics on the other hand I find just fine. MacBooks do this of course but there’s also a few x86 laptops equipped with pads like that.
So in my opinion, mechanical clickpads should disappear entirely and laptops should offer two options: a static haptic clickpad and traditional trackpad with buttons.
