I think the canonical example of 'unbundling' is every startup that does a thing that could be done via Excel and streamlining the experience around one use-case: time tracking for freelancers, inventory management, etc. I hear there's been a bunch of money made around making SaaS out of things that used to be done in Excel sheets.
Totally, outside of people trying to make a "smarter" excel like Airtable or Rows, different business units will make some "template" that lets them run their orgs in excel. Those "templates" could certainly be better products.
