Go onto any of the dedicated arranger forums (PSR Tutorial is one example) and you will find the vast majority are home hobby players. (Remember the arranger keyboard is just further development of the easy play features that first started out on home organs)

Says the organ player...
I disagree ith you..
Can you name on feature not on an arranger that a professional live player would ever need?
I think its acually home Players thats push arrangers forward..
Because they want more tools in their box to make fun with..
And they want them to be eas accesible..
They in general want the latest and greatest, and they can and want to pay for it..
And the pro’s they are the ones that profit from that...
