There's no reason there can't be. It just needs a policy deciding. Do we have: (1) One control for all. (2) One control for all non-root users; no quotas on root. (3) One control for root, one control for all non-root users. (3) Separate controls for all users. Should this be a ulimit? Should a non-root user be able to adjust their own quotas within limits set by root? How should the quota be accessed? The obvious way is to have /proc or /sys controls. Non-root quotas tend to be transitory. When the user_struct pinning them goes out of scope, they tend to disappear. How do we recover the settings, if at all?
