My understanding is that the expectation of this PR is to rewrite uuid to nil, so this expectation should actually take effect in embedded (the embedded structure is nil, or if the embedded has other fields that are not nil, then the field is nil).
But it cannot be done through the judgment of reflect.Array and field.OwnerSchema, and the judgment of reflect.Array is not easy to understand unless someone sees this PR.
From the expectation, I think the PR is only partially completed, although it does solve the problem in #7090.

-UserUUID  *datatypes.UUID
+EmbeddedUUID *EmbeddedUUID `gorm:"embedded"`

+type EmbeddedUUID struct {
+	UserUUID *datatypes.UUID

Yes I agree with you that this is not the cleanest way to fix this problem.

Using an embedded structure is much cleaner (and no code change here!), although I'm not sure how many users will be aware of using it when the problem arises - which is why I felt that we should support this way.

But if using embedded structures is the only right way, please feel free to close this PR. Thank you! 😄

I don't mean we should use embedded, but we should keep the same behavior as embedded.
You can wait for jinzhu's review.
