In reading the documentation on declaring Typed Data API data type plugins → , it says the following:
constraints: An optional array of validation constraints. This is unused in default implementations of TypedData. It is preferred to add constraints to the data definition instance instead.
I'm assuming that 'default implementations of TypedData' refers to data type plugins provided by core. However, the data type plugin definition for the Email plugin declares the constraint in the plugin annotation.
These two items are at odds with each other. Either the documentation should be altered to remove the mention of this method being unused by core, or core should be altered to be in line with this documentation. I'm not sure which one is correct however, so I'm not sure where to proceed in rectifying this situation.

Primarily changes documentation, not code. For Drupal core issues, select the Documentation component instead of using this tag. In general, component selection is preferred over tag selection.

It's likely this issue predates Contrib.social: some issue and comment data are missing.
The API page linked in the Issue Summary now contains an example that declares the constraint in the annotation. And that agrees with \Drupal\Core\TypedData\Annotation\DataType. so, I think this is outdated.
Therefore, closing as outdated. If this is incorrect reopen the issue, by setting the status to 'Active', and add a comment explaining what still needs to be done.
Thanks!
