Storage_check config option - undocumented for 3 years and running

What even is this storage_check feature?

references:

And there’s an issue open that requests at least some documentation related to this; #22895 - opened 3 years ago.


I would like to know because of another issue I am having, which is that project usage_quotas are not showing. This is also very poorly documented as the only doc related to it is user-oriented and there is zero documentation for the administrative side of it
