Without intervention, people should not notice any difference to current behaviour with the changes from these patches. Except the startup error additionaly listing the file, that's triggering the contact to a non-available network share.
I might have a slight preference to not see ISOs as essential files after a successful installation indeed, but there certainly are setups, where it does not make sense to attempt starting up a machine (or let the attempt fail) without an available ISO attached to the VM.
