Hello all! We've been working on a design for adding support for sending offer operation status updates to schedulers. You can find the design doc here <https://docs.google.com/a/mesosphere.io/document/d/1GGh14SbPTItjiweSZfann4GZ6PCteNrn-1y4pxOjgcI> .
TL;DR: Mesos currently provides schedulers with feedback when a LAUNCH operation succeeds or fails via task status updates. It does not, however, provide explicit feedback for other offer operations such as RESERVE, UNRESERVE, CREATE, and DESTROY. The plan is to provide feedback for these operations in a similar way. Comments on the design doc would be greatly appreciated! Cheers, -Gastón
