Sure. However, that makes the difference between O(1) and O(N),
where N is the number of releases recorded. Going back to your
original concern: you would not have to change the policy of
keeping many different releases if the number of releases
does not impact performance.

When it looks for individual release pages, does it know that these
are release pages, or does it follow all links on the package
page? If the latter, what links does it follow (there are plenty
more on the package page)?
