Deduplication support for content source
Windows Server 2012 R2 data deduplication is currently only for the content library on distribution points but not on the content source itself (https://blogs.technet.microsoft.com/configmgrteam/2014/02/18/configuration-manager-distribution-points-and-windows-server-2012-data-deduplication/). It would be nice to have deduplication support also on the content source. This might depend on the content source structure, but in the environments I'm working with, I have always different versions of application sources with only slightly different configuration files or just additional patch files.
