Sure they do, if they're 11'th order or more.  Part of the
problem is how you view "phase difference".  I would prefer
to talk of the group delay of the filter, which reflects how
different frequencies are *DELAYED* (which is what most people
care about), rather than the phase of the filter.  
Since all the nasty phase-shifting occurs at high frequencies, 
I still say, "who cares?"
