I don’t see why it wouldn’t work in principle as long as you have at least 2 items in the array. But it will fall apart when there are none or 1. Although I do not understand your purpose for using array_filter() and filtering all the values through strlen() as this would return an array of the string lengths of the elements.

$development = the_sub_field('development', $post_id);
$output = false;
if (count($development) == 1) {
  $output = $development[0];
} elseif (count($development) > 1)  {
  $last  = array_slice($development, -1);
  $first = join(', ', array_slice($development, 0, -1));
  $both  = array_merge(array($first), $last);
  $output = join(' and ', $both);
}
if ($output) {
  echo $output;
}
