Every country have their different policy against bitcoin but one thing for sure that my government are against with my bitcoin so it won't happen.
For me, when bank accept bitcoin it means that bitcoin consider as a fiat although bitcoin is an asset not fiat !
Bitcoin is most popular in nature , i know you will know, if they allow the bitcoin as a payment and bitcoin price drops there are will be problem for the bank iknow in the few years to come, banks will have to choice to start offering bitcoin transactions included the savings.
