Yes, exactly.

I have seen in the code comments/doc that the label is the raw name of the column, the prefix being applied only later, which must that

if self.is_custom:
        return '#' + self.label
else:
        return self.label

so when during my test I saw {"custom_series_index" : 77} appear, I was a little surprised.
However, on the GUI side, Yes, all works and the name is well prefixed

Well, it's only very marginal and obscure, and plugins like 'Manage Series' modify its fields without case. So I think somewhere along the way there and back, we lost a part without realizing it, since the car still runs perfectly. Oops?
