| I am supprised there has not been a beter answer yet.
heres my take on it. if the planed dive is only two hours long and it goes to shit and ends up at four hours it dont matter what you dive. when your suit floods it is not that long till you can surface.
two - four hours dives are short compared to some dives that are done. on these dives a flooded suit can be life threaternig because it takes too long to get to the surface and warmth. Its on these dives that some types of dry gloves are not used.
not used due to reduce risks involved thats all.
Now the real DIR clones will be along saying "one system for everything"
sorry dont have an answer.
