Optimization - I look at upgrading my lathe like this............. When I bought my pickup truck some years ago, I did not think back then about pulling a trailer. Since I got that truck I have now acquired two trailers and use them quite regularly, so that fact has necessitated that I upgrade my truck for that purpose. I put on a class IV trailer hitch back some years ago and also had a heavy duty clutch installed as well.....one that is optimal for towing and hauling heavy loads.
I think that it would have been wrong of me to buy a truck that had none of those features on it, and then expect that they should have had them installed, unless I paid for a towing package........which on my next truck will be one of the items that I will make sure is on the vehicle and of course will pay for that feature.
Adding accessories to suit our uses and purposes is a fairly standard thing with anything........including wood working equipment. On my former table saw, I made several upgrades to make it a better performing machine, and when I got my present table saw, I went for a premium Biesmeyer fence system, etc......all that adds to the cost.
Adding an accessory to optimize my lathe is in the same category in my thinking...........If I wanted many possible accessories included, then I would have to pay for those, so thankfully, they are available as aftermarket options, and I can tweak my lathe and optimize it for those purposes that suit my uses as I go along!
If I had wanted all the bells and whistles of a top of the line truck back then, I would have had to pay more than I did to get all those accessories.........the same holds true with our lathes......I believe I got a really good lathe with the basics as far a a package for far less $$$ than the higher end lathes out there.......and for those very substantial savings, I will be glad to add a little tweak here and there to optimize it, and customize it to my own liking!
