Yes, it would be very convenient to have such feature: remove the oldest
checkpoint if filesystem reached e.g. 80 %.
Quota, as you said, is about absolute limit. When we have dynamic
environment (often resize filesystems and have many filesystems)
recalculating quota is time consuming.

I am aware of this. However it is still not convenient.
