I mostly brought it up because the ticket also repeatedly mentions the default 
Mesos command executor. Supporting this one does not sound to different from 
supporting Docker without Thermos. It would also need similar logic at the UI 
layer to allow use the Mesos sanbox UI instead of the Thermos one.

I agree that we should not block progress here. I justed wanted to make sure we 
are not rushing things (i.e., there isn't even a jira ticket right now).
