Sure. Rub hits the road when it comes to actually implementing this,
though -- the issue of enforcing the limit without creating a bottleneck
to table extension is not trivial to overcome, as I recall. Right now
it might not matter tremendously much given that we only extending a
page at a time, but there's also been talk about extending in larger
chunks and that could become a problem.
If someone were to indulge in actual thinking and less handwaving, I'm
sure it would be welcome.
