I understand Signal's stance on this. For this vulnerability, the attacker needs physical access to computer. If the attacker has already gained physical access, the attacker can already access your messages, crypto wallets, password managers.
Many password managers also have this flaw. For example, Someone can change Keepass master password if the user is already logged in to the session, if they have physical access to the PC and lock you out of all your accounts.
Yeah, this is why I added a hardware key to my db. The hardware key is required not just for reading the db, but writing to it as well.
Another tip: use something like an OnlyKey that has its own locking and self-destruct mechanisms so this method isn't foiled by simply acquiring the key.
