Can confirm on both 29 and 28.  Although I think you missed the `&rest'
in the argument list, so you would only need to say

    (interactive nil #'text-mode)

In my testing, I tried to define:

    (defun foo () (interactive nil #'text-mode) 2)

Running M-x fo TAB while inside an `ielm' buffer completes the `foo'
command, which should not happen according to the quoted documentation.

On a slight tangent, I tried to use M-X (M-S-x,
`execute-extended-command-for-buffer'), and regardless of what major
modes I am in, I cannot find or call the `foo' command.

Best,
