Turns out that I don't have a use-case after all. I created some FLAC
compressed soundfonts, stored them in an SF3 file and did some tests
on my embedded machine. Loading times were significantly longer with
FLAC than with uncompressed WAV. So my loading times are not
IO-bound... oh well. The soundfonts are about half in size, so
transferring new soundfonts onto my instrument will be slightly
quicker. But that doesn't happen often enough to be a good use-case.

So, I second Garth's opinion and would like to pose his question
again: Does anybody have a good use-case for FLAC compressed
soundfonts (besides "it seems like a sensible idea")?
And is that use-case beneficial enough to justify opening up the
SF3/SF4 can-of-worms?
