Nothing is set in stone let alone rules about not hosting the Games in November. Let's get real. Most of the wealthy Western Europe bids probably won't happen due to local population objections. Hosting SOG only loses money and most people prefer the money to be spend on them rather than a two week sporting event. Montreal paid off the 1976 debt for like 40 years? I don't see them hosting another Games anytime soon.
The Winter Games became so exclusive they had to give it to China who isn't exactly well known as a winter nation. If IOC stays true to their diversification & inclusive nonsense they will have to pick an Asian vernue sooner or later. This probably means a return to China or Qatar as the obvious Middle East candidate.
London will not get another SOG after only 24 years again, Budapest, Istanbul and Russia don't sit well with the liberal values of the Wester world, Germany already rejected the WOG bid for Munich/Ga-Pa due to local protests, I don't see them hosting SOG either. Indonesia is the biggest Muslim country in the world and a complete unknown when it comes to hosting global events of any kind (unlike Doha). They went ahead with the Games in Rio de Janeiro despite objections about humidity & corruption.
When there is so much money involved things can change fast. And nothing devalues faster than a word "game-changer". These rules you cite could become irrelevant anytime between today and Brisbane OG.
