What is the expected behavior?

I expect to get the model updated and the change event called after remove selected options of the options list.

What is the current behavior?

The model don't update and the change event is not called, but visually is updated.

What are the steps to reproduce?

1 - http://plnkr.co/edit/RNAeZbaNrtMQRrjC7IDc?p=preview ;
2 - Click on "Remove options";
3 - mat-select visually update;
4 - model dont update and change event is not called;

What is the use-case or motivation for changing an existing behavior?

If I change the options for any reason, I expect to get the change events and the model to be updated in order to keep data consistent;

Which versions of Angular, Material, OS, TypeScript, browsers are affected?

master

Is there anything else we should know?

No

We will need to determine if changes should propagate as you described.

Personally, I think that if we do propagate some of these changes up, we need to have a different emitter for non selected value affecting.

@josephperrott even if be decided that changes should not propagate, it's necessary to have a way to force this changes thru the component api in order to update the model accordingly with the new set of options.

What do you think?
