For deployments of PSCore6.x it would make sense to have a very lightweight pkg that is essentially: Engine, PkgMgmt, PSGet, and basic cmdlets (like Get-Command, Import-Module, Archive module). This pkg would be mostly used on servers being managed and would install-module what they need.

Another pkg would be for the developer/it-pro which is very rich including everything in lite, but also modules useful for authoring and debugging scripts/modules: JSON, WebCmdlets, YAML module, Management module, HelpSystem, etc...
