2022 Medallion Status Accelerator

Is the accelerator program still applicable for 2022? On the website there conflicting information saying it ended on 12/31/21 but in the T&C it says 1/4/21 to 12/31/22. Do I only get bonus MQMs/MQDs if I fly Delta One? I thought it was for Comfort + too but when I pretended to book a flight the MQMs are the same for main and comfort. Also, any general tips for hitting Gold challenge (can only fly domestic within next 3 months)
