I think you have correctly identified dealing with small amounts while working

Since 2012 (IIRC) we've known that Bitcoin's non-overlapping
difficulty calculation was vulnerable to gaming with inaccurate
timestamps to massively increase the rate of block production beyond
the system's intentional design. It can be fixed with a soft-fork that
further constraints block
