As the JustMock profiler needs to be registered into the Windows registry we need to research if such access permissions are available in hosted VSTS environment. We already have this logged as a feature request into our internal backlog. I have created a public item for this feature request
in our feedback portal as well. This way you could subscribe to the item and receive status updates. Once we start working on the task the item will be updated.
Regarding when this feature can be expected, I can't provide you an exact time frame as it is not scheduled yet.
Could you share with us some approximate date for when you would like to migrate to hosted VSTS? If you consider this an internal information you could open a support ticket and share the information there.
