It's certainly true that the 4-8k page size was chosen to match vorbis.
The only other cons I can think of to larger pages are higher
latency and buffering requirements if it's multiplexed with a
lower-bitrate stream. Also, keep in mind that when multiplexed with an
audio stream, seeking signposts will be more dense than if you use big
pages for video efficiency, so there's a performance tradeoff there.
