I'm not sure what distinction you're drawing. Continuous integration is entirely synonymous with trunk-based development.

It's true that as an industry we've overloaded the term Continuous Integration to mean build servers running automated tests (I just did so in a comment in this thread!), but that's where the overload is.

The overload is the absence of feature-branches and PR/MRs with review. A git-flow-like model and CI are fully compatible. OPs model is explicitly incompatible.
