How to linearize your cluster

In the discussion of blockchain transaction processing, the focus shifts to the concept of clusters within a network not necessarily needing to be identical. This is based on the premise that the primary goal is for the received linearization of transactions to outperform or demonstrate improvement over conflicting transactions through Child Pays for Parent (CPFP) mechanisms. This raises questions about potential vulnerabilities and the feasibility of an attacker exploiting these systems in various manners.
The inquiry delves into the specifics of how an attacker might leverage differences in cluster configurations to their advantage, questioning the potential outcomes such as enabling free relay of transactions or hindering further optimization of the network's graph structure. Despite the theoretical possibilities, there remains a lack of clarity or concrete examples illustrating how these attacks could be executed effectively. The discussion points towards an underlying challenge in fully understanding the implications of non-identical clusters within blockchain networks and the security considerations that accompany this architectural choice.
