I have some severe doubts about that.
For it to support FLAC, the playback application would need
to passthrough FLAC.
Which means someone needs to standardize a way to signal
that FLAC is supported for passthrough AND specify a passthrough
Considering how rare FLAC is, I really don't think anyone
has done that.
(of course it also doesn't really make any difference at all
who decodes FLAC anyway, but that is a different point)
