I would probably lean more toward using 3 for 32-bit samples, because
7 could increase the likelyhood of false sync codes occurring if some
of the other reserved bits came into use. absent a strong demand for
32 bit though, I would prefer to leave as is due to the disruptive
effect of defining new bits.
there is probably no problem with 32-bit being or not being in the
subset. subset decoders can reject unsupported sample rates; at the
same time I think any application handling 32-bit samples will not
be constrained in a way the subset tries to mitigate.
