Hi @tonyacollins-sm
It might be easier to answer your question if you provide some context.
A Service Offering is not a CSDM-authored term; it has been present since IT Service Management became a practice as a way of breaking down a service into separate packages.
Whether you use Service Offerings or not, this will have little to no impact on the integrity of the CMDB, other than eliminating the purpose of aligning with CSDM - to make your CMDB service-aware (or more accurately - Service Offering-aware).
Service Offerings are critical for describing the products an organisation develops to provide value to customers and employees, understanding commitment levels and SLAs, identifying and communicating service outages, and service reporting. With just Service records you have only the most basic understanding of what your organisation provides. Even if you have no more detail than just the Services, it's recommended to create a single Service Offering for each Service.
I hope this helps!
