In my experience large Microsoft customers deployed applications with SCCM, now perhaps moving to Intune. Distributing MSIs via group policy is fairly primitive compared to what endpoint management platforms can offer. But my point was that large commercial installer kits were always required to produce MSIs, in the absence of something like the WiX Toolset.
