Why is most DataTable functionality dependent on the Editor build configuration?


We want to runtime parse CSV files to use the data ingame.
I managed to do everything in code, but only now I see a number of functions which I need, need the Editor build configuration. main entry point: CreateTableFromCSVString(…)

Why is this? And is it something that I can bypass?
Where can I see if a matter like this is on the UE roadmap?
