The PS5 and XSX are so similar, I cannot help but laugh at that notion. The only devs that may still opt out of XSX ports (without a money hat) would be smaller japanese devs for different reasons than you stated. But even then, most of those games will be showing up on Switch as well, so still not exclusive in most cases.
The same applies to MS, no one is going to pass on the PS5 without a money hat. There is a reason MS is buying up developers, as 1st party games have become more and more relevant each gen.
