Not sure if this helps or muddies thing even more, but I just wen through 400+ pages of the part 107 rule. The only references to flight logs are in the Docket Comments section (see below copied right from the part 107 rule the last paragraph I think addresses the issue, but if someone disables that logging, then it would seem there's no problem:
Several individuals said small UAS should be equipped with flight data recording systems or “black boxes” so that operators can be held accountable for infractions. One individual said that, for those aircraft that can record flight log data, there should be a requirement to preserve that data in the event of an operation that causes injury or property damage. The commenter further suggested that, in case of airspace violations, the FAA consider requiring all such flight logs be kept for some predetermined period of time.
Due to the mitigations provided by part 107 that reduce the likelihood of a small UAS flight resulting in significant injury or property damage, a requirement to equip small unmanned aircraft with flight data recorders would be unnecessarily burdensome.
The Washington State Department of Transportation, Aviation Division said documentation of maintenance should be required for small UAS operated over large assemblies of people, such as professional sporting events, large concerts, and “similar environments where a safe landing area is likely unavailable.” NetMoby suggested that operators should be required to log the results of each preflight inspection for inspection by the FAA if needed.
Under Executive Order 12866, the FAA may “adopt a regulation only upon a reasoned determination that the benefits of the intended regulation justify its costs.” Imposing maintenance or preflight-check recordkeeping requirements, such as the ones suggested by the commenters, would likely result in a significant cost because the remote pilot in command would have to create new paperwork every time that he or she conducts a preflight check, or every time that any type of maintenance is conducted on the small UAS. At this time, the FAA does not have data to determine whether the safety benefits of additional documentation would be sufficient to justify this burden, especially in light of the significant safety mitigations already provided by the other provisions of part 107.
One individual suggested that a remote pilot in command must enable and make available to the FAA any flight log recording if the aircraft and/or control station is capable of creating such a recording. In response, the FAA notes that this rule does not require that a small UAS operation have the capability to create a flight log recording. However, if a small UAS does create such a recording, § 107.7(b) will allow the FAA to inspect the small
