Email validation is impossible

[BelfordZ]

There is no universal email validation, and I suggest that the language be loosened around this, for example.

In many places, there have been choices to make things up to the implementation. Perhaps this is already / should be one?

In OAS 3.1, JSON Schema draft 2019-09 will be used, and as noted in #2093, format validation is disabled by default. For exactly this reason.

@webron @MikeRalphson I think this can be closed in favor of #2093 which will cover it. Unless we want to do something separate in 3.0.3, I guess.

@handrews - agreed.
