When it comes to medicine, in the real world there are many times there are no retries because the treatment doesn't work. Or maybe you can try a second time but it's a higher DC.
Isn't a limited number of tries (potentially 1) try a "cost"? I view it as trying to treat an infection with the equivalent of antibiotics, but if that doesn't work you have to try something else, or a stronger antibiotic. Maybe you failed the first time but since that treatment didn't work you have to fine some rare herb which fires off a side quest.
If you can do multiple tries and will eventually succeed then I agree there is no need for a check. That's why I'll either just allow success or limit retries.
