As discussed in #16 and on mattermost, there are a number of columns in various tables of Pandora, that only seem to serve as placeholders to be filled from other tables up- or downstream in the Pandora hierarchy. Imho they are pointless and confusing for data analysis.

I see three options how to address that:

1. Do nothing and keep the fake columns around (as suggested by @ivelsko for the ethics columns)
2. Populate them from the actual data columns in the other tables (as suggested by @trhermes)
3. Delete them in the process of and behind get_df()

I don't like 1. for obvious reasons (and generally consider the ethics issue solved with the startup message). 2. is tricky to pull off and would force a lot of data download even if one only wants a single table. So 3. it is, in my opinion.

What do you folks say? (including @jfy133)
