Agree, for me, being a storage admin in a previous life I had the Storage admin 
here add migration rules to migrate these datasets that have not been 
referenced in 10 days.

Only concern would be users creating datasets with DATE/TIME entries and there 
is no cleanup. 

So you could have a user create 365 Date datasets * hhmmss entries and then not 
have a process to DELETE the things no longer needed. 

I will use the inappropriate term - ga-zillions of datasets in your DASD 
Volumes and no clean up.
