Possible side effects include:
- If their user_nicename also changes, then their /author/$name URLs will
break. That said user_nicename is different from email, so that's
manageable.
- You need to make sure to properly invalidate the cache for a username
change.
- Nausea, dry mouth, blurred vision, headache.*
That said:
It's one thing to allow username changes, but I don't think your use case is
the right one. Rather, there are plugins and hooks available to allow you to
authenticate based on email, rather than making the username equal the
email.
