Journal publishers are increasingly mandating data sharing activities, sometimes more than certain funders. These data sharing requirements can also be required for an article to move to editorial review, and may even hold an article from publication.
Look for the data sharing requirements of any prospective publisher you wish to submit a manuscript to, and see if they recommend or support integrations with data repositories. See an example from American Geophysical Union.
