Why is GenerateCode called twice?

[vikstrous2]

Reading the code in api/generate.go, I see codegen.GenerateCode(data) called twice. Once before plugins run and once after. Why is this? It seems very wasteful. I see that there was an attempt to remove it in #1079 but that had to be reverted. I see that some things don't work correctly if it's removed. Is anything more known about why? What exactly needs to be done before vs after plugins run?

@vektah can you provide some info about why #1079 was reverted? Do you see any way to avoid calling GenerateCode twice?
