In most fields papers / articles are still the one critical metric crucial for career advancement. You will sit on data and code until you are ready to publish, sometimes for years.

Datasets and analytical code must be regarded as a scientific achievement on its on, albeit not as substitute for the "full" substantive analysis in a paper.

A social science PhD in Denmark, for example, must write two to four peer reviewed papers at the moment. The option to substitute one of the articles with a data set?

Things get better though: People nowadays at least understand my citations better, since I cite at least the explicitly included R-packages used in my work.
