 I think this approach is preferable to removing callbacks to `the_content`
 since it solves both the "double execution problem" and the "avoid all
 execution problem" I detailed above. Thanks @flixos90 this looks
 promising.

 I do, however, agree with @manfcarlo that the placeholder string approach
 may have weaknesses in certain circumstances, though I'm not sure what
 mitigations can be applied given the string format of the raw data. Tough
 call.
