I tested a single input --> output conversion to compare performance and 
I noticed the final report now displays N/A for time, bitrate and speed i.e.

frame= 1500 fps=109 q=-1.0 Lsize=   17363kB time=N/A bitrate=N/A speed=N/A

whereas commit 1439784ff0 shows

frame= 1500 fps=108 q=-1.0 Lsize=   17363kB time=00:00:59.97 
bitrate=2371.6kbits/s speed=4.34x

Is this expected?

I do see values *while* transcoding.
