Could you possibly create macros to a) remove or at least rename a VFS item, b) remove an account, and c) sort the account list like you can do in the GUI.
If you don't want to create the first two for security concerns, I understand but consider that even without removing them it's still possible to completely destroy any information they contain or purpose they have even if they still inevitably exist. For example:
{.set account|person|enabled=0|newname=[deleted]|notes=|redirect=.}
for destroying an account or for a VFS item using overwrite with a new, blank folder:
{.add folder|virtual|folder|overwrite=1|diff template=nothing.tpl.}
