> Everyone ignores it and tries to reinvent their own idea of what the standard could be. Sure, but that's not a failing of developers, the standard just happens to be too complex to validate without language or module support. If JS had an isValidEmail() function everyone would use it and be consistent, but without one the options are to google up some massive (but still imperfect) regex, or accept any string with an @ sign in it somewhere, or choose some random point in between.
