I get your point, but a west coast is not exactly the same as an historical IPA, do we stop calling them IPAs too?
I understand your point in pastries, which in my opinion should be called pastry blond, or pastry pale or whatever as they are not hop focused as an IPA (an american, the original wasn't that much hop focused) should be, but you regular NEIPA it's just a result of a better management of both brewing water and hops to extract its best potential, is it wrong to call them IPAs? I don't thing so, I particularly think west coast and NE should be different in name, but without stripping any of them from the IPA surname
I myself have suffered the feeling of thinking I was going to enjoy a West Coast as I was feeling like that at the moment and finding something called IPA was in fact a NE and the reverse way too, there is a brewery in my country that doesn't differentiate too much their IPAs, they do it sometimes but not always, I bought an IPA that was supposed to be a NEIPA as they mostly brew that, I wanted a NEIPA that day and I got something piney and bitter, it ruined my day, well not really, but I wasn't happy about it
