Odoo removed an underused setting that automatically added user signatures to email templates because it could create confusing or duplicate signatures. Templates that still need a signature now include it directly, making email content clearer and more predictable for users.

The field user_signature wasn't used that much and when used
it caused some issues so it has been removed.

Existing templates that had the user_signature field set to True
were modified to include the user.signature.
