That will never be sorted out. It's completely different hardware / tracking method.
the tracking method is almost certainly not the issue. you can use PSVR1 as a PC VR headset (you shouldn't cuz it's shit, but it works)
the real reason is Sony doesn't want "dirty" backwards compatibility for their shiny new device.
why "dirty", well because no matter how you do it it will be confusing for some customers (the casual filth, the bad potatoes so to say).
you could be of the opinion that they should support all PSVR1 games, which is Option #1, but here's the issue,
this is the controller used for PSVR1:
you have 5 digital face buttons on each side, you have a start and a select button on the side in each hand... and you have a singular trigger in each hand.
and now this is what the PSVR2 controllers look like:
on the left you have 2 face buttons and the left stick, on the right you have 2 face buttons and the right stick.
you have a grip button and a trigger.
the right controller has the Menu/Start button and the left one has the Share button.
imagine what a shitshow it would be to map all of the PSVR1 buttons onto these controllers. it would be a nightmare of overlays that are needed to configure the controls for each game and remind the player where each button is mapped to.
Left Stick Up = Right Hand Square... shit like that
and then there's option #2,
only make games compatible that work with the Dualshock 4,,, well... sure that would fix the button config mess for sure,
but now you have customers that need to understand which PSVR1 game is compatible and which isn't so that they don't accidentally buy the wrong game.
now tracking does become an issue as Dualshock 4's would need the PS4 camera to work with that setup and Dualsense controllers would need to be programmed to emulate the tracking through the inside out tracking, which might not be possible with Dualsense controller because that's not how the tracking cameras inside the PSVR2 are designed to work, they are designed to track small IR LED light dots, not big blue/red/green light bars around the touchpad.
add to that Sony's really bad/manual system to issue refunds (the singular reason why Cyberpunk 2077 was removed from the PS Store) and you got a customer service nightmare at hand.
option #1 would be a convoluted mess of button rebinds and overlays to remind you of all your rebinds.
option #2 would be a convoluted mess of people wondering which games are compatible and which are not.
both of these would confuse the average casual filth user and would make the whole system look unpolished (or as I named it "dirty").
and such dirty features like this kind of back compat functionality is often avoided by electronics manufacturers that want their shiny new product to feel polished and well designed.
