Oh this is where the title goes?
If the PCs are particularly concerned about a saving throw in my games, then they will tend to work for Inspiration for themselves or someone else will give up their Inspiration for the player about to roll the save. So I think this is an issue that's mostly resolved by the rules as they currently exist.
True, in my example, Alice using her turn to comfort her frightened friend could reasonably be taken for inspiration, so it works out the same.
