Its more of a recent thing, but I am a little worried about how common it is becoming. I've used my GV number since atleast 2007 for everything.
My bank accounts at banks I like have never complained about my Google Voice number and still don't. My bank account at Bank of America had some security check I needed to complete at some point and my Google Voice number that had been in their system for a decade I was told was not eligible anymore and I needed to actually use my real phone number.
I could almost put up with it if it was for things that need to be secure, but my 7-11 rewards account rejected my phone number at the gas pump a few years ago and Target rewards also started blocking my GV number.
Some may call, most not even that.
