Imagine you got your license and then tasked to make a crud service with some simple UI because that is what is needed for the client and they cannot use unlicensed developers.
You'd also see service providers start selling pre-PE stamped services - which is hardly different from the whole "go buy your SaaS from X who is (compliance regime) authorized" today. Just like today when you build a house, your general contractor goes and buys a pre-engineered truss and hires a bunch of laborers to put it up per spec.
