I find it does not as long as you add it as a book format via Calibre.

Once calibre sees that original_FMT has been deleted, it's not then going to know that it is back again when manually extracted from the rar or via a rename. Maybe a library repair will pick it up again but what a rigmarole, compared with turning on a select epub as source format conversion option.
Even though in practice, I've not ever really needed the library mainenence tools, why deliberately do stuff that will mess them about.
It easy to open the RAR (via Calibre) and then drag-drop a file from the RAR archive back into Calibre so that it knows it is there again.
