But you can set a breakpoint, by clicking in the fringe, using the code that
you wrote (the local variable gud-minor-mode needs to be non-nil, though).

I would prefer to have just one approach. If the general preference is to
use the fringe then I'll move the breakpoint icons there.

This certainly makes the fringe more attractive.
