True. PS has platform-specific API hooks that are orthogonal to the capabilities of other shells, and more-less replaces JScript, VBScript, and .bat files.

Putting that stuff aside, it is/was one of the first command shells/REPLs outside of SQL DBMS ones in a long time to support manipulation of structured information. For a smoother transition, shells like nu that can straddle structured and file-/line-/word-oriented will be more successful than leaping to too radical of upheaval.
