This is still an issue on current master (and 26.2).

I reproduced this using:

    (progn
      (defcustom foobar nil
        "foo"
        :version "27.1"
        :package-version '(foo . "1"))
      (describe-variable-custom-version-info 'foobar))

Which results in:

    "This variable was introduced, or its default value was changed, in
    version 27.1 of Emacs.
    "

But C-h f defcustom says:

    :package-version
            VALUE should be a list with the form (PACKAGE . VERSION)
            specifying that the variable was first introduced, or its
            default value was changed, in PACKAGE version VERSION.  This
            keyword takes priority over :version.

Thanks,
