 - As other certificates are collected, third-party certifications that were previously unusable may become usable again. Dropping third-party certifications as a part of minimization prevents this mechanism.
 - Removing component keys that the minimizing implementation can't use means that the receiver does not receive a copy of those, even if *the receiver* supports them.
 - Refreshing certificates from key servers may inflate the certificate again, since OpenPGP certificates tend to act as [append-only structures](append-only).
