Comment (by s7r):

 Just to make sure: the option is enforced only when Tor '''wants''' or
 '''needs''' to generate new signing key and certificate (like when the
 signing key and certificate it has loaded in memory are going to expire
 soon), and is ignored otherwise?

 I have deleted ed25519_master_id_public_key and only left a valid
 certificate and signing key, and sent a HUP signal to Tor, it reloaded
 just fine but did not generate and write to disk
 ed25519_master_id_public_key from the certificate, as we normally do when
 we start.

 This has no importance - the behavior is correct either way just want to
 make sure I am describing it correctly in the documentation.
