This is supported and it work. You can live Migrate VMM from VMM (on a Hyper-V 2012 R2 Cluster). Use your vote for a ask better feature ;)
this idea is being under review. Once we have more information, we will be updating the status.

Abolutly agree, we can control HVR from Cluster console, we need to be able to control all the feature from VMM.
This feature is being planned, will update once we start working on this.
Dealing with large cloud need multi site library management.
There is no native replication mecanism build into VMM to do this, but it's not the worst from my opinion.
Equivalent object management it totally horrific and you have no mean to automate because there is no Powershell command available !
This is something that can eliminate VMM as cloud management tool for large projects.
