Chip contacted me at one point via their live assistant randomly without my doing and told me to stop using the app because they would soon be enforcing that rooted devices would no longer work. I continued to use the app rooted and nothing came of it.
Barclaycard, Nationwide and others don't let you use the app or require some circumvention of their detection to allow access.
Sure there are plenty of other apps, but those apps and banks have a worse product I found.
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.
