The apt-key man page mentions that the " use of apt-key is deprecated, except for the use of apt-key del in maintainer scripts to remove existing keys from the main keyring". This approach often makes it possible to build a chain between an arbitrary key and the key of someone you know and trust personally, thus verifying the authenticity of the first key in the chain.Both when encrypting messages and when verifying signatures, it is critical that the public key used to send messages to someone or some entity actually does.
