There's no laws banning this in any European countries that I'm aware of, except maybe Hungary? It's just banks being stupid, consumer-hostile, and anti-competitive.
Well, I've built a bunch of mobile banking apps and we did detect if the phone was rooted, was in dev mode, etc. and it is not because we were "stupid, consumer-hostile, and anti-competitive".
If someone steals the secrets from a rooted phone and steals customer's money the bank is on the hook, so banks do everything they can to minimize this risk.
There is no way to store customer's secrets in a PC browser securely, so all the "dangerous" transactions were outright prohibited in the web app or made available only via temporary QR login.
All this is just is a negative side effect of customer protection laws.
