Hi Patrick, there is no particular reason other than that this template has not had much demand from users so far, especially when compared to the other templates. Adding templates for all emails sent to end users is on our roadmap.

Personally, the point of having email templates is to maintain brand and style consistency between website and emails. Having inconsistent emails being sent to end users is not acceptable for me. The feature might as well not exist if I can't make edits to all of them.
