Implicit Deletions and Improvements in Utreexo IBD

The recent advancements in Utreexo technology show considerable promise. However, there are concerns regarding its integration with SwiftSync, another emerging technology. The primary worry is that this combination might impede the maturation process of Utreexo. Despite these reservations, integrating SwiftSync could potentially accelerate its own development pace, presenting a dual-edged scenario where both technologies could either benefit from mutual enhancement or suffer from premature integration. This dynamic poses a significant risk-reward scenario that merits careful consideration as both technologies evolve.
