Yitchokm: It’s not that Hanhaga can be changed based on current popular perception, it’s that maybe it can be changed due to new circumstances or a new understanding of Rishonim. Poskim are Mechadesh all the time and are sometimes even sure enough of that to Pasken by it. And we change Hanhaga. There are plenty of places we’re Machmir in Yoreh De’ah because we don’t know technical definitions anymore. Or people who decided to stop eating Gebrochts. Or plenty of other examples. There is no reason why things like MBP should be inherently different from those, even if in reality there is a different conclusion. But there’s no reason not to ask and look into it.
