expression="" is meant for system properties the user can specify on the
CLI and nothing else (MNG-2063). Fetching values from the project and
other sources should happen via default-value, independently from the
question whether those values are @readonly or not to the user.
These are transitive dependencies of maven-project. I don't believe
that it's necessary to declare used dependencies that are expected to
be transitive from higher-level dependencies.
Those dependencies are directly used by the APT Plugin and hence denote
*direct* dependencies of it which should be declared as those. Not doing
so is an anti-pattern which was one of the reason for dependency:analyze [0]
