Why do we need anything more than HTTP GET, PUT, POST?

Question

What is the practical benefit of using HTTP GET, PUT, DELETE, POST, HEAD? Why not focus on their behavioral benefits (safety and idempotency), forgetting their names, and use GE

Answer 1

You could use only GET and POST but then you are losing out on some of the precision and clarity that PUT and DELETE bring. POST is a wildcard operation that could mean anything. PUT and DELETE's behaviour is very well defined. If you think of a resource management API then GET, PUT and DELETE probably cover 80%-90% of the required functionality. If you limit yourself to GET and POST then 40%-60% of your api is accessed using the poorly specified POST.
