Signal's nickname feature can protect you from accidentally adding the wrong person to a group chat
-
Encryption can’t protect you from adding the wrong person to a group chat. But there is also a setting to make sure you don’t.
You can add your own nickname to a Signal contact by clicking on the person’s profile picture in a chat with them then clicking “Nickname.” Signal says “Nicknames & notes are stored with Signal and end-to-end encrypted. They are only visible to you.” So, you can add a nickname to a Jason saying “co-founder,” or maybe “national security adviser,” and no one else is going to see it. Just you. When you’re trying to make a group chat, perhaps.
Signal could improve its user interface around groups and people with duplicate display names.

This shouldn't really be necessary, as Signal uses the contact info in your contacts by default.

That only works if the Signal user gives others access to their phone number (and you have that number saved with a suitable name in your phone’s contacts).
