Why is the price (commerce_price) blocked from being removed from product variation types?

Issue Summary

I tried to look for this in the documentation, but I have not found any answer.

I want to define the price of the items on a store, inside the product itself and not the variations, since that is the client's requierement.

I can't seem to remove the field from the variation types and when I try to, the field says it is blocked and cannot be removed. I might be missing something important here, as to why is that field blocked and tied to the variation type, something that I might not be aware.

Is there a way to remove that field from the variation type? Why should/should not do that?
