@darrelmiller can you add a sample for that in the YAML files please?

I need to think about how to model this in the OpenAPI.

[darrelmiller]

Implement special method on RequestBuilder that accepts something like:

   graphClient.Users[<id>].PatchBulk(Delta<User> userDelta );

ewww.

I don't think any of that has ground in OpenAPI semantics. OData has some semantics for delta patching, although I've only seen it used when listing changes (change tracking/delta queries), never used from the client updating the data. I'm going to close this, we can always re-open when OpenAPI has semantics for that. Also, if an API supports that can of semantics (delta patch via annotation which is not a defined property), they can already do that through the additional data manager today.
