[ome-users] Deleting an object together with its directory in ManagedRepository

[Andrii Iudin]

Dear Mark,

Thank you for explaining the current situation. I will check with my 
supervisor if we can allocate resources to implementing this, however, 
please point to the relevant code.

I agree that the nature of this request is rather specific. This is due 
to the way our weekly release process is done - we end up syncing 
ManagedRepository and empty directories seem to slow down things. 
Hopefully, we will be able to do the PR.

Best regards,
Andrii
