As per documentation MSM works in AEM assets.
Limitations and known issues of MSM for Assets
Following is a limitation of MSM for Assets.
- Content Fragments (CFs) are not supported for the use case. When attempting to create their live copies, CFs are copied over as is without any relationship. The copied CFs are a snapshot in time and do not update when the original CFs are updated.
- MSM does not work with metadata writeback enabled. Upon writeback, the inheritance breaks.

I want to know how to enable maintain master and live copy relationship if this is not provided OOTB. I think there should be a strong reason why it is not enabled for CF. Is there any reason ?
