It depends where you are.  In Australia, the bandwidth limit is 8kHz 
on 160-12 metres.  Good amateur practice would dictate that you don't 
use wider eSSB when the bands are crowded, but when the bands are 
relatively clear, I don't see any problems, provided the legal 
aspects are taken care of.  I would like to see bandwidth limits 
imposed by amateurs operating within the law and processing 
limitations, rather than arbitrary limitations.
