It's important to realize that for banks IT is a cost center. Sorry, that argument doesn't float in the overall scheme of things. TOTP is easy to implement, more secure and costs less to operate than SMS verification --- which is widely supported by banks and in many cases is really nothing more than TOTP codes transmitted across the cell network. If IT cost was really the issue, TOTP would likely be the universal default option.
