After some testing during development, it looks like the web server update that I thought would cause the site to completely stop functioning wouldn't be as serious as I initially thought. I forced the upgrade to happen immediately while there's still an option to downgrade again.
As such, please let me know immediately (PM or email) if you experience any issues with the site so I can undo the changes.
Hopefully this bought me some time to fully flesh out OOPSS v3
