They've all started cracking down, in the past year the Barclays and Lloyds app have broken on my phone.
TSB still works for now, but even for a bank they're technologically incompetent so I'm going to just assume they're behind the curve rather than willingly not using SafetyNet.
The only one I would bank on still working in the future is Monzo, since, like you say, they detect it and just give you scary warning and let you continue.
