[optional] is it necessary to download all the scripts to ~/.dataretriever ?

[RMHogervorst]

I wonder if it is necessary to download all these jsons and python scripts to your ~/.dataretriever folder. This seems overkill/wasteful if you want to use 2 of the ~200 datasets. I get that the total load on the system is small, the files are small and diskspace is cheap, even bandwidth is cheap in most places, but could it be done smarter? Maybe this is more a general dataretriever issue?
