Why hasnt a turntable manufacturer produced a table with automatic tonearm return/shutoff?

High end turntables are focused on the absolute best possible sound, adding a mechanical device to lift and/or return adds noise and reliability problems. 

Little Fwend is your little fwend....

Here's a link to a google search of "Little Fwend" that shows the Little Fwend tonearm lift, as well as offerings from several other manufacturers.

I have a B&O 1900, built in 1976 fully automatic. I won’t but a manual table due to the inconvenience of placing the tonearm and having to get up when album side is over., I play 1/2 an album at night then switch to streamer. There are a few automatic TT’s made today Dual, Denon, Project, Thorens.. 

Seems to me the mere existence of the Little Fwend and vs other tonearm lifters reflects a problem that needs solving. I’m just saying I’m surprised such mechanisms are not incorporated into the initial design of high end turntables along with auto return and shut off. Some people just don’t b like getting up every 20 minutes when the side playing is over. It’s hard to get off the ground for some of us😎

I only use a tonearm lifter (I use the Audio Technica version which is much less expensive than the little fwend and does precisely the same thing) because the noise at the runout groove is too jarring after the music stops playing. Also, I would never leave a record on the platter once it's done playing, so what benefit would there be to this scenario? Of course, this is all at a spry 56 years and I might well feel differently when and if I'm less mobile.
