A few reasons I suspect:
1) Not needed on a well set up and correctly balanced boat
2) Of no use for lower speed applications such as semi-displacement boats
3) If used on semi-displacement boat it could have the effect of making them run "nose down" slightly.
4) Then can cause handling problems if fitted to a well balanced boat, making the stern high caused by the lift - if they were built in by the manufacturer, they would need to be removable.
Also, I personally feel they are only of use with power trim, so you can control the amount of lift/trim effects.
They are of most use to stern heavy boats, or boats that struggle getting on the plane (ie towing my best mate on water skis- he's not the slimmest of people shall we say
