Comment (by desrosj):

 In chatting this through with @fishtron and @pbearne, @swissspidy's
 suggestion above to not save a value to the database for the two options
 unless a non-default one is entered/selected seemed like the best approach
 at first.

 However, it seems that this will cause problems within plugins and themes
 as using `get_option()` to
 [https://wpdirectory.net/search/01K7MRP6YQVRKKCAK5A9EQ9V6H retrieve these
 two values directly is quite common] (acknowledging that this site is not
 up to date with the current state of the directory for several months).

 Here are some additional observations:
 - When the `F j, Y` format is not the default for the active locale, the
 form renders with `\c\u\s\t\o\m` as the selected radio button and `F j, Y`
 (which is a pretty common and standard date format) is not available as an
 option.
 - It may be nice to include something to the effect of "(language
 default)" next to the top option to make it clear that format is the
 default.
