How often do you come across flexible hoses that have been disconnected after use? Since they're invariably left connected a rigid connection would make no practical difference, providing of course that it included the double check valve and decent isolating valves.
In fact a small modification could provide a filling point that was inherently safe - unlike the existing filling loops. If the isolating valves either side of the check valve were three way valves so when shut from filling they were open to discharge into, say, the PRV discharge pipe, any failure of either isolating valve or the check valve would result in a discharge to waste which would be visible.
