Power management is a critical part of any install. A simple rack can become a mess with 5V, 12V, 24V wall wart adapters, power strips, and all the other associated power cabling. Having sockets include different power types and adapters would be a huge help. Battery backups, power conditioners, sequencers, all take up rack space as well and need to be factored in to the rack builds. It would be a huge help to have those elements included in the schematics and rack builds.
