[arch-general] Why has all Fake-RAID documentation been removed from the RAID wiki?

Arch, In the past https://wiki.archlinux.org/index.php/RAID had a fantastic section on Fake RAID. I just had a person I refered to the page only to be told there isn't any relevant info there other than use lspci to look for a conroller?? Why has all the relevant information for Fake RAID been removed from the wiki? It is still relevant documentation. -- David C. Rankin, J.D.,P.E.
