No, but I don't like the vague threat of permanent disadvantages hanging over my head. I wouldn't mind if the effigies were more like traditional consumables that enemies could drop, because then at least there would be some breathing room to play around with them and figure out when they should be conserved and when they should be used. But with a strict limit on how many there are, there's no recourse if you discover that you should have used them on this other point in the game when you have none left.
Also, if you kill them enough times, enemies stop respawning when you rest at a bonfire. That worries me. Okay, it'll be helpful to not have to kill the same enemies I've killed fifty times before on my way to a boss, but what if I really need to farm souls? Again, it's like the game is putting artificial restrictions on my ability to recover from mistakes.
