This is an extremely dangerous command you just suggested and overkill as well. There is no need to have the "-r" option which will recurse through folders. If the user makes a mistake with the path, it could wipe out a lot more than is intended. I am assuming the extension you listed is just a single file and not a bundle folder.
Plus, when deleting a single file, especially with a "-f" force option, it is wise to add the "-i" option so that the user is prompted to confirm the deletion as it will print the item about to be deleted. When used with the "-r" option, this could alert the user to a problem if more than one item is prompted for deletion...of course they may not realize it until the second item is prompted, but it will minimize the damage if caught.
Keep in mind most people reading these posts will not be familiar with the command line and the risks involved by a simple mistake.
