I know that pid.codes checks that you have actual, published open source code before he'll allocate you one. There's no reason to have one before that point any

I know that pid.codes checks that you have actual, published open source code before he'll allocate you one. There's no reason to have one before that point anyway: you can always use a test code. It's only once the general public will be using it that you need a real, unique code.
