Description

we also need a good explanation written down of the difference.

• default-value is used when expression is null
• expression is intended to be used to get the user's override, eg from a system property

Perhaps if we could cover that other use case differently (eg by a standard system property mechanism that went [plugin-prefix.goal.configuration]), we could eliminate expression altogether in a future version of Maven.
