It comes from that commit:

commit 0957b274e312e985d69cb490bee2a7ff820acaa6

    lavc: add an option to enable side data-only packets during encoding
    Some encoders (e.g. flac) need to send side data when there is no more
    data to be output. This enables them to output a packet with no data in
    it, only side data.

IMHO, the empty packet should not be reaching the demuxers that do not
expect them, that would change the output. I suggest you check with Anton.
