Hide Content in Notification Emails

Hello, we implemented Gitlab in a protected/confidential environment.

Every time someone comments on an issue, or tag somebody, we receive email notifications about it - which is great, but it comes with the content of the message, which is not end-to-end encrypted.

Our environment requires confidential info to be end-to-end encrypted when sent through emails, and Gitlab emails are not encrypted.

So we need a way to keep notifications, but disabling the content showing in the Gitlab email notifications.

For example, if John replies to my comment, the email notification I receive should only say: John replied to your comment, view here: link_to_comment - without the content of the comment in the email.

Can we disable the content from showing?
