I think the issue is if it's not cleaned afterwards, you have this 
ammonium compound or acid (either way, pretty reactive) stuff in a box 
which is closed up.  Obviously, it's not going to severely corrode the 
copper (although, over time...) I think the concern is with other 
components.

And, of course, when doing flow soldering, they use a very reactive 
flux, but they also wash the board afterwards.
