Well, not entirely. There are some who are perfectly able to pass a 3rd Class medical, yet opt to go for the SP certificate for reasons completely separate from health concerns. Those folks often use SP as a quick and easy entry level license, and later use it as a stepping-stone toward higher ratings. About 25% of my students fall into this category.
Yup i get it. But my proposal says passing a medical is unnecessary. And by breaking down the PPL you can get into flying in say 30 hours... Just not night without add-in endorsements. And complex and or high performance would be add-on endorsements, too. Under my proposal no medicals (sans whatever it takes to get drivers license) until you become a pro and start doing this for hire.
Just an idea.
