banks really like hardware attestation and putting that in laptops and PCs causes serious pushback from people like us here. not an option to not have hardware attestation on mobile - it's been there since day 1, there's nothing to protest against anymore
I think for many banks, Wero will be implemented in the banks' apps (like iDEAL currently is). So then the situation is probably the same as now (where most, but not all banking apps work without Play remote attestation).
