Your statement doesn't seem true. In neither of the files you mentioned is there a string 'completecontent' to be found. Always assuming I can trust my BBEdit search, of course.
In fact 'completecontent' occurs in one place only, as %\completecontent in strc-pag.mkiv, that is all. I excluded mkii files in order not to mix things up between mkii and mkiv.

: I tried to find the definition of \completecontent in the source, but searching for it doesn't turn up its occurence. Where do I have to look?
The \completecontent command is created with \definecombinedlist[content].
The definition for \definecombinedlist is in strc-lst.mkvi but \completecontent is defined in strc-def.mkiv
