It is not around what you do, it is about that I then have to clean the mess it might cause. If you then want to explain and help every user that when he flashes back a DreamOS image strange things (like recursive symlinks) could happen you are welcome, if not then better stay away of such things you hardly understand.
Cleanly erasing and re-filling a mounted filesystem is a tricky thing and at the end I have to support it. I have seen what happened to dFlash after I made it Open Source and gave up development and if you want to force me doing this also with dBackup you will not make many friends.
It is nice if you test and point out that something is not working anymore, but you either are patient or you will have to live with the consequences. If I support plugins for Open* Images or for OE2.0 boxes the support is always passive and when time permits and this will not change.
