Its part of Unix and its well defined and used by applications, both for hitting quota (the easy bit), checking quota (when checking space for things particularly), and manipulating them
The latter bit is nice, it means you can mount with a user quota set in the mount options, and if you want then use quota tools to change the quota of a specific user or two that have special rules.
