In my opinion, extremely unsafe.
i seem to recall that the prelim report for the mismanaged Emirates 777 go-around in UAE was released within 30days of the event and was of decent quality. If one expects level of quality from ATSB we’re dreaming.
I was waiting for a ground staff lightning strike report to develop some policy and procedures whilst operating on the ramp area during thunderstorms, some time back. Took 3 years to get to a final report after about 3 different delays (the prelim was just a statement of facts and took a year to come out)!! WTF! In the meantime, everyone is left vulnerable and exposed.
Much in the same way as you’ve said (if I’ve understood you properly), the final report said nothing of worth. No accountability! Nothing.
Useless bureaucrats!
