Title: Adding New Feature: Suppress Cancel During Process Install/Uninstall/Repair

MSI technology allows several [ways] (http://msdn.microsoft.com/en-us/library/aa368791 (v = vs.85) .aspx) to suppress the abolition install / uninstall / repair. Why not add this feature in the WixStandardBA? It doesn't affect anything and very cheaply to impliment.
