Editing Credential template after Issuing

[kayaelle]

Once a credential has been sent in a batch, should we freeze editing of the credential template? It seems ok to edit the email template but what happens if someone edits the template after a batch has been sent and then does a new batch with the edited template. Won't that affect the previous batch's credentials when they claim them if they do so after the credential template has been updated?

Let's consider freezing the template after a batch has been sent and allowing for it to be duplicated with its own distinct name - even with copy in it). That way each batch will know which version of the credential was issued to which batch.
