I wonder why these power cords do not have a simple GFCI in-line breaker
that would trip and warn the user when any of the connections are
starting
to go.

That would be nice. Probably only cost an extra $25 or so.

What's strange is that the 2002 NEC requires that GFCI outlets be installed:
"outdoors, in boathouses, in buildings used for storage, maintenance,
repair, where hand tools, diagnostic equipment, or portable lighting is
used", but has no GFCI requirement for shore power.

Even specifically states that these requirements are for "Other than shore
power"

Makes no sense to me.
