And that is precisely how the National Library of Australia's software 
seems to be using it. However, it is a recording format in one instance 
which I own:

 From the current Samplitude ProX2 manual:

Samplitude and the RME Fireface UFX both directly record in WAV files.
The Fireface UFX uses a poly WAV file (as do the SD products) to avoid
having many open files.

Samplitude exports to FLAC directly through commands.

So, at least in my world, FLAC support is fairly broad, but, Lou, as you 
state, it is not used directly for recording (in my world) except for 
the SD722 (and I do not use that feature).

When Exact Audio Copy rips a CD to FLAC it first rips to WAV and then 
runs the external FLAC compressor, but although that is the way it is 
often used, the presence of the SD capability indicates to me that it is 
a stand-alone format, not an accessory.
