Agent: storage houskeeping, reducing file space

Please implemet a agent houskeeping mechanism to prevent that the agent is storing too much old data:

Example at our hosts:
du -skh /var/lib/check_mk_agent/
301M /var/lib/check_mk_agent/

Please keep the agent storage smal as possible.
The best would be to have rules for such storing data to have the possibility to define: store only the last 10 agent entries/updates. and delete old log files older than 100 days, and so on.

Thanks
