Welcome message out of the box regardless

I know this has been discussed before but I do think that being able to immediately display the "Welcome_message" would be beneficial rather than having the unfriendly "Whoops! We seem to have hit a snag message..." appear...

May I propose the following additional JavaScript script which I think is far more informative:

file: system/Cache/Handlers/FileHandler.php

PHP Code:

/**
* Constructor.
*
* @param  type $config
* @throws type
*/
public function __construct($config)
{
$path = ! empty($config->storePath) ? $config->storePath : WRITEPATH . 'cache';
if (! is_really_writable($path))
{

// PROPOSAL START
$aTmp = [
 'Unable to log Errors and/or warnings', 
 'Please set ../writable folder permissions to 0777',
 '../writable folder permissions not set to 0777',
 'Please consult manual regarding ../writable folder',
 '\t\tWhoops! \n\nWe seem to have hit a snag. \n\n\tPlease try again later...\n\n',
 'Better suggestions welcome \n\n\t\t :)\n\n',
 'Shit happens :(',
 ];
$tmp = $aTmp[mt_rand(0, count($aTmp)-1 )];

?>
<script>
alert("<?= $tmp ?>");
</script>
<?php
// throw CacheException::forUnableToWrite($path);
// PROPOSAL FINISH

}//endif

$this->prefix = $config->prefix ?: '';
$this->path  = rtrim($path, '/') . '/';
}//endfunc 


Please note the additional script always shows if and only the writable folder is not writable instead of the following exception:

PHP Code:

  throw CacheException::forUnableToWrite($path);
