Change in fastCloning default value
We've come across this many times on microboone: if we change a data product and attempt to read in old data, output will fail with a hard-to-diagnose error due to the fast cloning being turned on by default. While I understand that it's more efficient to leave it on (when appropriate), I really think it would be better to have it "false" by default, and have people turn it to true if they know what they are doing will be ok with it turned on. That should lead to fewer head-scratching errors.
So ... can I request a change in the default for the root output fast cloning to be false?
