My bank is detecting Netscape Navigator 4 & you better bet it’s a horrible experience for small viewports, & generally a buggy experience altogether (scoping other sites in my country, they are all just as bad).
This is also presupposing the Google doesn’t get its Web Environment Integrity (WEI) initiative foisted upon us allowing the banks to do the same sketchy attestation that they can do with apps from the browser--meaning they could deny you from running an alternative OS, disabling TPM/Pluton/Secure Boot, to having admin/root access like they block it on phones for dubious reasons.
