Please reread what I wrote. I said that `completing-read' is
not mentioned in node `Basic Completion'. And it is not.

So what?
If the bug is that a user will not know the details for a
function-valued COLLECTION argument to `completing-read' then the
right place to send a reader for __that information__ is node
`Programmed Completion'. That is specifically the purpose of
that node. And that is the _only_ place that info is provided.

No one said that that is true. This bug is about that particular
case.
The point is that mention of a function-valued COLLECTION in the
doc string should get readers to `Programmed Completion'.
Read what I said. I did not say that we should send users to
`P. C.' for general info about COLLECTION. I said:
`Programmed Completion' is where we should send someone for
information about a function-valued COLLECTION argument.
^^^^^^^^^^^^^^^
And I said, regarding general info about COLLECTION:
It doesn't hurt to send them to both nodes or to only
their parent, `Completion'.
What is inadequate for the function-valued COLLECTION case, is
to send readers __only__ to `Basic Completion'. Especially with
no indication that they need to consult not only `all-completions'
and `try-completion' there, but also `test-completion'.
That's the missing info, if you send them only to `B. C.': no
info that `test-completion' is relevant to the function-valued
COLLECTION case for `completing-read'.
