Why set a pagination limit? For sites with lots of posts, this should speed up your build time considerably since Jekyll won't have to generate and write so many additional pages. Additionally, I suspect that it is very uncommon for users to browse paginated post indexes beyond a few pages. If you don't like it, it's easy to disable.
