I completely agree that salt creep would be enough to keep a manual float from closing. I also think salt creep could also cause a float switch to fail as well.
For redundancy using a mechanical float switch, I would position one mechanical float slightly higher than the main float. Should the main float ever fail, the higher float would cut water to the failed float. My thinking could be flawed but I've read quite a few reviews on BRS and people swear by them. I am new to this and definetly no pro so anyways those are just my thoughts.
