No. If you successfully unmount a filesystem it implies that nobody else was using it at that time. If you remove a data medium without having its filesystem unmounted first can lead to application crashed or worse (data loss). A possible correct behaviour would be to send an unmount request to all process currently using the filesystem/medium in question on eject requests and remove it when it can be savely unmounted.
