I've tried to revert back an NSF ODS, as I've done since Notes 8, but I was unable. I've detected this behaviour in Notes 12.0.2FP5. I'm sure it worked in Notes 12.0.2FP2
C:\Program Files (x86)\HCL\Notes\Data>"c:\Program Files (x86)\HCL\Notes\ncompact.exe" -r log.nsf
[E48C:0002-E7DC] The ID file being used is: c:\Program Files (x86)\HCL\Notes\Data\user.id

Is this so, or maybe my procedure is not correct ?
