I've posed that question here on the list about half a year ago, and
nobody had to report anything negative... so yes, I'm wondering as
well why the default isn't "9200 off the shelf".
One possible thought I had was that it could affect the internal memory
layout, with a larger MTU segmenting the memory into fewer + larger
buffers, but nobody was able to confirm that - at least not for the
6500...
