The other SCOTUS decisions about Roe v. Wade, etc. mostly only affect people on the lower tiers of the power hierarchy. The people at the top may or may not like it, but they are isolated enough to not have to deal with it on a personal level.
But this decision about presidential immunity directly affects the dynamics of power. The other people in the game will have to react or they will likely end up losing power. The balance of power will find a new equilibrium, for better or worse.
