Of course this will cause some mischief to server owners whose users can't differentiate version(s)
Best solution here would be diligent server owners. Each Jenkins build would have it's own linkable page and a server owner that is doing their job would have a 'mod list' with direct links to each specific versions' page.
By all accounts the video that started this contained a bit of (forgive me, Kane) nerd-rage, and the discussion could have gone much worse if it had been handled differently.
