As discussed, we want to emphasize positive notifications over negative notifications, by listing them first in the Echo user preferences.
As a rule of thumb, we would also make some negative notification types opt-in, so the user would have to purposely select that option in preferences before getting emails about them.
With that in mind, let's move 'Reverts my edit' to the bottom of the list, since it is both negative and opt-in.
The purpose of this feature is to encourage notifications that make users feel positive about their contributions to Wikipedia:

In general, we propose to list notification preferences based on the order of priority and frequency shown in this section.
