Default X351 Sunroof frame vs L405/L494

Just wondered if anyone had knowledge of if the Range Rover L405/L494 sunroof frame rust issue is just as widespread in the X351? I can find a new posts of older X351's with sunroof frame rust issues but I hear so much about L405's having issues that it seems much more common on RR than Jaguars and that surprised me as I assume they would make both sunroof frames in the same way, I am of course wondering if I should take preventative maintenance on my X351 although I cannot see any issues at the moment...

This is some stuff on the RR sunroof frame issue I am talking about Someone that just fixes RR roofs,
, and
Brass repair pipe Brass repair pipe
.

Thanks

It's been reported and repaired but I think the fact that a LOT more RR's were sold compared to the X351 cars is why you see so much more about it.

​​​​​​​It is a late 2017 but a 2018 model year so maybe that had the fix in it?

Yes, I can see how that could be, hence why I thought it could be as much a problem as a RR...
