As mentioned in the comments, plain text keys aren't bad because they are necessary. You have to have at least one plain text key in order to be able to use encryption

No, why would a backup contain non-exportable information? One of the reasons to use TPM to begin with is that sensitive information can't leave it.

How do you restore a backup on another phone without the keys?

You would probably use a recovery key that exists exclusively elsewhere like on paper in a vault. Like bitlocker.

I have no idea if signal uses TPM or not but generally keys in TPM are non-exportable which is a very good thing and IMO the primary reason to use TPM at all.
