Well, here's my kneee jerk reaction.  Last night I started converting
all breakpoints to use breakpoint_ops, and I immediately stumbled on
the fact that the print_one method doesn't appear to work as is.  I
don't like the idea of exposing the API as is and getting stuck
with it when we haven't even made sure it's a good fit for
gdb's own regular breakpoints.  :-(
