No, because it provides no evidence in support of either of the two prominent Nord Stream sabotage theories: (1) the Seymour Hersh account and (2) the rental yacht narrative.
When the findings from important investigations are delayed, information leaks serve to control the narrative and satisfy political or economic objectives. Why are these intelligence organizations so eager to assign blame within the Ukrainian government? Why are the actual findings of the investigations not being released? Perhaps the WP and Spiegel reporters can answer those questions.

According to the joint research by DER SPIEGEL and The Washington Post, Chervinskyi’s name is circulating both in Ukrainian and international security circles in connection with the attack on the Nord Stream pipelines. The former agent allegedly coordinated the attack and also provided support for the specialist unit behind the sabotage operation.
Cautionary note:
People in Western security circles say that the Ukrainian security apparatus is plagued with rivalries and infighting, and that information obtained from sources there must be handled with caution.
