Yes but it pushes it to an operating system level and that means everyone wins as the operating system solutions to improve as vulnerabilities are found and resolved.
You also don't need rce access to exfiltrate data. If decrypted keys are held in memory, that mitigates an entire class of vulnerabilities from other applications causing your private chats from leaking.
Full disk encryption is not a solution here. Any application that's already running which can provide read only file system access to an attacker is not going to be affected by your full disk encryption.
that's my point
