Why a full keys and sub keys backup are not proposed when keys and sub keys are done "on-card" ?

A lost of a signing or authentication key is usually not that
problematic.  You can simply create a new one and use it from then on.

If you don't have access to the decryption key anymore you won't be
able to decrypt any of the data you decrypted in the past to that key.
Thus some kind of recovery is in most cases very useful.



Die Gedanken sind frei.  Auschnahme regelt ein Bundeschgesetz.
