Nice to have features list.

This issue is like TODO and random-access roadmap in one to transform problems and suggestions to the code. "opt-in" features should be totally optional and tree-shakeable. The list is subject to change.

• [feat / dev] Use releases to track important changes between versions https://github.com/manishsaraan/email-validator/issues/60
• [feat / config] Some configuration https://github.com/manishsaraan/email-validator/issues/20
• [feat / important] IPv6 compatibility: https://github.com/manishsaraan/email-validator/issues/59
• [feat / important] utf compatibility. Three PRs are open regarding this. One of them is https://github.com/manishsaraan/email-validator/pull/57
• [feat / important] Load tests. Due to previous hypothetical changes, it can become slow or an attack vector. Should test execution time against some tricky dataset.
• [feat / node / opt-in] MX-record validation as opt-in. Influenced by https://github.com/manishsaraan/email-validator/issues/65
• [feat] More strict flags and/or allowed symbols somehow. Influenced by https://github.com/manishsaraan/email-validator/issues/71
• [feat] Universal esm / commonjs bundling to shake that tree being modern and a bit compatible. Will introduce some runtime requirements bump, hence major release.
• [feat / easy] https://github.com/manishsaraan/email-validator/issues/66 Maybe.
• [feat] Private domain check as a (plugin??). Influenced by https://github.com/manishsaraan/email-validator/issues/70

@manishsaraan Looks like this is complete list of requested and technically needed features for now. Could you please take a brief look at the list ?

I think, the first step should be moving away from one regex or construct it on the fly. The first major problem is to work with unicode chars safely. For now I see an incremental way to do this by explicitly allow some narrow ranges, starting from requested Thai and: Chinese, Korean, Japanese, Ukrainian, Kazakh and Russian characters. Have asked a native speaker here. Hope, he would help to safely include Thai.
