The feedback BTS received regarding confidentiality was based largely on the old forms. Therefore, BTS does not know how the changes in the forms impact the confidentiality issue. Also, before the final rule was published, carriers did not have a mechanism for requesting confidentiality. Now individual carriers can request confidentiality protection based on a competitive harm standard. If a carrier meets the standard, BTS must withhold its report from public release.
Carriers can also request an exemption from filing based on a similar standard.
In order to know what further protections are needed, if any, BTS must review how effective these new mechanisms are. In sum, in order for BTS to accomplish its goal of striking an appropriate balance, it needs to gain more experience with the major changes it recently made. Gaining experience and additional information will also be critical in solving several problems pointed out in the comments. Not only would this preclude the presentation of many of the meaningful findings, but others would not be able to examine and critique their work. Similarly, it is not clear whether safety researchers outside of academia would have access, although safety is certainly a concern to many others.
