AWS MSK Cloud Formation Tags problems

When creating AWS::MSK::Cluster with Cloud Formation I am not able to set Tags in the usual way:

      Tags:
        - Key: Name
          Value: !Ref Identifier

Because of this error:

Property validation failure: [Value of property {/Tags} does not match type {Map}]

As of the time of writing, the documentation states that, instead of the usual Type: List of Tag, I should use: Type: Json.

Also the same documentation states that:

You can specify tags in JSON or in YAML, depending on which format you use for your template

After further investigation (and AWS support help), the working (only on creation) example looks like this:

Tags:
  Name: !Ref Identifier

Additionally, tags cannot be modified (the docs actually state that tags change require replacement), when tried a slightly confusing error shows up:

CloudFormation cannot update a stack when a custom-named resource requires replacing. Rename kafka-eu-west-1-dev and update the stack again.
