I have a possible use for FLAC for realtime audio.
We (Overte, an open source VR environment) have a need for fast audio encoding, and sometimes audio encoding CPU time is the main bottleneck. For this purpose we support multiple codecs, and FLAC is actually of interest because it turns out that the niche of "compressing audio really fast but still in good quality" is a rare one.
We maingly use Opus which is great, but it's fairly CPU heavy, so there can be cases when one might want to sacrifice some bandwidth in exchange for less CPU time.
