Templating API object size limits?

I am learning the Curlybars templating API, because I want to try to change how the “Articles in this Section” works. For example, if we have 11 articles in a section, it's not a great design from a UX perspective to have the reader click “See more”, taking them away from the current page, only to see just one additional article in the list. A more robust article navigation tree on the left side of the page would be preferable.

But, according to this page, section.articles has a size limit of 10 “for performance reasons”.

Similarly, on the section page where the “See more” link takes you, the section.artilces size limit appears to be 30 - I would like to show more than 30 per page here to eliminate the need for pagination in our larger sections, to try to improve the navigability of our documentation.

Can anyone expand on why these particular objects are so limited for performance reasons? And, are there any ways around these limitations? Thanks!
