I'm sure we've all built scripts that avoid this kind of problem, but it would be cool if Grouper could handle the really obvious cases.

Yes, I think that would be useful.
In this case, I control the process, but I can envision scenarios where I can't.
Also, I think I'd feel better knowing that there was a failsafe on Grouper.

Not at the moment, it will sync with the table.  Is there a way for the process the updates the table to not truncate first and just add/remove as needed?  :)  I could add an enhancement in the loader if you think it would be useful

Is there some way to tell the Grouper Loader to abort a sync if it detects a big swing in group membership?
I am thinking of the case where we have a process that populates a data warehouse SQL database and the loader populates reference from it.
If the job failed and left a table empty, is there a way to tell the loader not to alter the reference group?
