Should next gen systems be fully Backwards Compatible from Day 1 to encourage people to upgrade?

I keep my old consoles anyway, so it doesn't make a big difference for me. Unless there's some reason I don't want to plug in my old system, or maybe it's malfunctioning in some way.
But I probably never will buy a console Day 1 any more. Last time I did that was PS2.

How about the PS4, do you think it will be completely compatible with PS4's PSVR? The move from the PS3 which is used with the PSVR, or even things like the controller from the PS4 when you need to use the motion control and the little mouse touchpad thing on it? I think games which rely on specific hardware... Skylanders and Starlink both come to mind again where they have a thing which needs to connect to the PS4 in order to play. I can't see both systems being able to give 100% backwards compatibility.

Things that required the touchpad or motion controls would not work if those features are excluded from the Dualshock 5.
I expect there to be a PSVR2 though, or the ability to plug in the original PSVR. It hasn't reached amazing numbers, but it is still the best selling VR headset on the market, so they should continue.

Would think a solution to this would be to allow the ps5 to use the DS4 but then you possibly undercut the ability to sell ps5 controllers, the flip side of that is looking at the Switch, you can use almost every controller with that machine if you got the adapter for it all the way back to use old GC pads for 8 player smash bros, could be a way to allow full backwards BC and the only real cost would be hardware sales to people who love collecting hardware anyway so they'll likely buy the DS5Pro and then be happy to have that for ps5 games and use the DS4 for the titles which require it.
