Just because some places implemented the validation wrong does not mean the validation should not occur. The validation is there to catch user mistakes before sending a validation email and ending up with unusable account creation. |

It doesn't matter if an email has a valid format: that says almost nothing about it's validity. The only way you can be sure an address can receive mail(today) is by sending mail to it. All the rest is theatre.
And all this only matters if the business cares about deliverability in the first place.
