Just re-read the entire thread. Arguments for adding this were:
Fun for players on a higher level than their friends.
People who chose double time can chat during the final waiting time.
Players who don't choose DT don't have their experience changed in any way.
Allows most lobbies to cater to specific players without specific map choices, just like other freemods.
Arguments against:
Not actually physically playing in real time with the DT players.
People can show off with DT.
People who pick DT will have to wait at the end of the map for other players.
People who pick DT might leave before the map is over (just like any mod choices I don't even understand this point).
I'll just state my opinion again, there is no disadvantage to ANYONE by adding it. If people argue that it shouldn't added for any reason I can conceive they're literally saying "I don't want you to have fun".
Just gonna quote this for people who are too lazy to read the thread:

The idea would be that none double time players and double time players would start the map at the same time. As they play the none-DT players would have the scores of the DT players fed to them as if it was nomod with a + 0.12 modifier (essentially they would see the DT players performances at the same stage as themselves throughout the entire map). At the end of the map the DT players would have to wait for other players to finish the map at which point the results screen would appear.
This would NOT change the appearance of multiplayer AT ALL for none-DT players and it would NOT change the pace that scores are delivered to them. The argument that halftime should be allowed has been brought up too but that would mean that all nomod players would have to wait for HT players to finish which I don't think is fair.
And of course if peppy was feeling particularly generous some sort of activity could be added for player who use DT (such as spectating other players while waiting or being able to view the scores of all players live) but really the DT players should expect to wait and don't deserve this compensation.
