The maximum size of blocks in between doublings will increase linearly based on the block's timestamp. The maximum size of blocks after 2036-01-06 00:00:00 UTC shall be 8,192,000,000 bytes.

Would that block have a lower size restriction again? Would using block height not be a more stable number to work with?

In the nVersion bits proposal that I co-authored we solved that issue by
comparing the timestamp against the median time, which is guaranteed by
the protocol rules to monotonically advance.
