   > Earlier, I mentioned that the MCS could not include source operators due 
to certain ECM constraints. However, I have since identified a simple solution 
to address that issue, so this restriction has now been removed.

supported. I’ve updated the PR description to explain the reasoning behind this 
decision.
   
   I am actually fine with excluding source operators. On the technical side it 
might be hard. Our implementation of source is a process function of one single 
special kick off tuple. This means the entire state of a source operator is 
associated with this single special tuple, which is hard to be broken and 
transferred.  On the use case side, reconfigure a source operator is less 
useful: if you need to change the source (e.g., read another csv, fetch from 
another api/db), it's likely you need to rerun the entire workflow.
