We can certainly add text to point out that this is a limitation of RFC 
6716, e.g., "The duration of an Opus packet as defined in RFC 6716 can 
be any multiple..."

For 48 kHz, we might say, "It is possible to run an Opus decoder at 
other sampling rates, but all of them evenly divide 48 kHz. Therefore, 
the value in the granule position field always counts samples assuming a 
48 kHz decoding rate..."
