Maintaining PHP 5 documentation

Hi team,

I landed on this plain 404 page yesterday:
https://www.php.net/manual/en/ini.sect.safe-mode.php#ini.safe-mode

I was told that the PHP 5 docs are in the process of being removed from
php.net. This is not ideal for me as I maintain and migrate legacy
applications for a living.

I would like to understand the reasoning behind this decision and perhaps
offer some help to remedy the situation:
- Are there any inherent problems with keeping the legacy docs online?
- How much effort does it require to maintain the legacy docs?
- Are there any associated costs?

Thanks,
Anna Filina
