I think as long as the default when not running interactively is to dump
core
we are OK.

Having the two defaults being reversed (n followed by a y) would be a
little
uncomfortable.  But you could change the wording instead if you really
want
to change the interactive default (I sincerely hope people are not used
to
answer this question already ;-), so there wouldn't be much impact with
the 
change).
