 There should be an option to display custom field data without having to
 acquire a plugin, rely on a theme supporting it, or hack a theme; surely
 this can be achieved in core, programmatically. Options could/should
 include (in order of importance):

 Global Admin settings to:
 1. Enable/disable the display of raw custom field data in a post
 2. Option to rewrite outputted field data (add wrapper) that may include
 HTML
 3. Specify where in a post, the field is output, depending of available
 hooks
 4. Specify optional regex validation
 5. Specify optional data regex replacement on output
 6. Specify which options above, are returned via the API to other plugins
 7. Specify optional CSS for any classes and IDs added in (2) above.
 8. Specify whether a custom field should be a requirement/optional
 9. Specify where the custom field box should appear on the post edit page
 10. Option to rewrite outputted field data using PHP snippet

 Even implementing only items 1-3 would provide a powerful and flexible way
 to manage meta data, and provide WP v5 with a significant improvement over
 earlier versions.
