That is the actual reason. For example, use Iron Dome to take out air dropped bombs rather than use a more expensive Barak-8 or Derby/Python.
Despite brochure claims, there is no omnipotent system. Which is why in an Indian Army platoon you find Carl Gustaf, MGL-40, RPO Sheml, Shipon and Spanish C90. Which is why surgeons use multiple scalpels. If a sangar needs to be taken out, an LCA makes more sense than a Su-30. If a missile boat needs to be taken out, one uses a Uran missile instead of Brahmos.
