Comment (by boonebgorges):

 In [changeset:"31006"]:
 {{{
 #!CommitTicketReference repository="" revision="31006"
 In `wp_dropdown_categories()`, allow the term field used to populate
 option valuesto be specified.

 The new 'value_field' parameter makes it possible to set term slugs (or
 some
 other term property) as the 'value' attribute of the option elements
 generated
 by `wp_dropdown_categories()`. This additional flexibility reduces the
 effort
 required to translate term_id to other term fields when processing form
 submissions that include values from taxonomy dropdowns. See #30865 for a
 use case.

 Props collinsinternet.
 Fixes #30306.
