We should be reducing the amount of data exposed and fixing the mistakes of the past that allowed so much data to be easily exfiltrated.
> Best experience first.
"Best" is not a defined term. What software developers should (always) be providing is the safest method first. Fancy UI tricks are a far lower priority than safety. If there is any doubt, fail safely.
Anybody that isn't putting safety first is being incredibly irresponsible. Stop leaking data and design for safety and security first. Yes, this it will be harder to make a nice user experience. In time, this will improve, but in the meantime safety is not something that can simply be ignored.
Safety is not an optional feature that only some people should have.
