Should “national-film-registry” be a keyword?

In any case, "national-film-registry" is a valid keyword for titles such as These Amazing Shadows (2011) or this podcast, both of which discuss the NFR itself as a primary subject, while not being inductees themselves. As for adding it as a keyword to titles inducted into the registry, yes, I agree that this is not really a valid use of the keyword system. However, I understand that the users adding it as a keyword have somewhat of a good reason for doing so. Adding it as a keyword is basically a work-around that allows users to filter their lists to see which titles on that list have been inducted into the registry. Of course, a filter capable of doing this already exists in the Advanced Search, but this filter is not accessible to users viewing a list page directly. If IMDb were to add an 'awards' filter to the currently available list filters, it would render the "national-film-registry" keyword obsolete, and nothing would be lost by deleting the keyword from all of those titles.

Hi @timothy_gray_el34lojg1aih1 mentioned, the usage would be acceptable in those specific instances. Thanks!
