Those callouts are typically made by the pilots. In the 737 the V1 fallout has been added because it is generated by the aircraft and I plan on adding that aircraft specific callout to other aircraft that have it.
The other callouts are not by the aircraft, that's just standard procedure, then everything should be announced, like gear up, flaps up, set heading XYZ, etc. You see how much work that would require? That's why it's not added yet.
