This option is pretty useful to select keys based on their properties.
The scope thing can be sued to limit a selection to just the primary
key or to subkeys.  For example:

  gpg -k --list-filter 'select=revoked-f && sub/algostr=ed25519'

Lists all non-revoked keys with an ed25519 (signing)-subkey.
