Some developers write their own regular expression(regex) to validate email which usually does not support IDN emails since a regex that supports IEA will be too complex and hard to write and debug . A standard library that has a function like validateEmail() eases the support for IEA in web and mobile apps development . I wish the UASG considers contacting open source software vendors like (Microsoft,php.net or openjdk.java.net . etc.) to include email validation in their standard libraries or to sponsor an existing library to be the official email validation library and be the reference implementation for other software developers.
