No comments on Russia rework getting frozen? David Gaider used aprently work on it before focusing on Summerfall Studios.
There are some pretty big differences between why Russia and India were frozen, which are being overlooked by most observers. I don't have a 100% insider perspective, since I don't work on Russia myself, but key differences include:
1. India was frozen because its foundational lore had a mixed reception in the community. Russia, on the other hand, has been well received across the board.
2. As can be seen in PRs, Russia is in a far more complete state than India ever was, with clear designs for gameplay and some features at or near implementation.
3. As stated by team members in the comments for a recent PR, Rylock's departure wasn't the direct cause of the rework's freezing. His primary partner, who continued the rework, is currently busy with other more pressing work. Given that we as a team just got saddled with the largest update to HoI4's fundamentals since launch, if you put two and two together, it's reasonable to assume said developer won't be preoccupied indefinitely.
