(replying to the base message because there are a few separate threads
going).

Thanks for these inputs and sorry for my late reply.
So according to Jake Magnum still requires SoftwareDeployment/Config. I got
one off-list reply
from the user using the feature. Based on these feedbacks, we can keep the
feature for now.

The main challenge with keeping this feature is that we have to maintain a
specific image with
additional tools installed. We can try our best to keep these maintained
but if anyone can help
maintaining the job/tools, test the features and share any test feedback,
that is much appreciated.
