Support for snap-ins

PowerShell will not support the legacy version of modules, also known as snap-ins. Many of the snap-ins of old have been repackaged to be binary modules. Therefore, the unavailability of snap-ins should not be of much concern. Future development of these binary modules should, in theory, work on either PowerShell, provided that the host supports the API calls that are part of the binaries. For example, let's imagine that the Windows Active Directory module was repackaged into a binary PowerShell module. This module would run on Windows PowerShell as well as PowerShell on Windows. However, since Windows Active Directory does not run on Linux, the module would not work with PowerShell on Linux.
