PHP 8.3 deprecate second param to array_keys

[andrewnicols]

As noted in the RFC PHP 8.3 deprecates the second parameter to array_keys() to apply a filter.

The following uses of a second filter param to array_keys can be found in tcpdf:

The sgugestion is to combine array_keys and array_filter. A new method may be added in PHP 8.4 but does not exist yet.

tcpdf.php:                                                      $xshift += (count(array_keys($uniarr, 32)) * $spw);
tcpdf_barcodes_1d.php:                  $k = array_keys($chars, $code[$i]);
tcpdf_barcodes_1d.php:                  $k = array_keys($chars, $code[$i]);
tcpdf_barcodes_1d.php:                  $k = array_keys($chars, $code[$i]);
tcpdf_barcodes_1d.php:                  $chk = array_keys($checktable, array($row,$col));

The page https://www.php.net/manual/en/function.array-keys.php does not mention any deprecation.
The page https://wiki.php.net/rfc/deprecate_functions_with_overloaded_signatures#array_keys shows the majority of the votes (15) rejected the proposal. What I am missing?
