That could be a first approximation.  However, the completion shipped
with zsh may be spread across multiple files (Command/_foo and
Types/_foo_thingies) or be in a differently-named file (the completion
for groupmod(8) is in _user_admin, the completion of latexmk(1) is in
tex(1), ...), and I haven't said a word yet about whether
{foo}.zsh_completion uses more advanced features such as tags,
descriptions, and matchspecs.

In short, I don't have a rule of thumb for you.  What I can say with certainty is
that if both zsh and foo upstream provide completion for foo, a bug report
against either or both would be worthwhile so as to reduce duplication of effort.

HTH,

Daniel
