I want to make a Drupal view showing CiviCRM Relationships and I want to expose the start and end date as exposed filters.
I want the user to have a nice GUI for picking the start and end date so I installed the required modules for displaying a jQuery date picker.
However, the CivCRM Relationship Start and End Dates do not seem to be recognised by Drupal as date fields.
I am trying to follow these instructions on how to properly set up a date filter on a view:

But as you can see from the screenshot, I am unable to do the first step, because "date" is not an option in the "filter" dropdown.
I can select the start and end dates anyway, of course. But then I do not get all the date-specific options like "Date selection form element" or "Filter Granularity".
Am I right, or am I missing something?
Do you know if any attempts have been made to fix this in core?
Interestingly, when setting the same fields as sort fields, they do seem to be treated as dates:
