Homebox entities do not save "real" blocks / entities

Problem/Motivation

Homebox entities do not save block objects, but rather pseudo block arrays in the form of:

[0] => Array
                (
                    [id] => system_powered_by_block
                    [title] => 
                    [weight] => 0
                    [region] => first
                    [status] => 1
                )
[2] => Array
                (
                    [id] => system_branding_block
                    [weight] => 0
                    [region] => second
                    [status] => 1
                )

Proposed resolution

Lets discuss, if we should save "proper" blocks in the homebox, or if this is unnecessary / impossible, since we cannot save specific data in a block instance?
