Commonly used? I doubt anyone has even given this combination a second thought. I can't imagine having a set of books that the title and author are wrong in the metadata but the rest of the metadata is good.
I either know the books have good metadata and add then using the metadata or more often than not I use filename to give me author and title and use download metadata to retrieve the rest of the metadata. Download metadata can be configured to not overwrite author and title. I use the Quick Preferences plugin
to switch between the various add books methods I use and select the appropriate Regex as required.
I use the following metadata download plugins
Barnes and Noble
I only download tags using the Goodreads plugin
which gives me a nice consistent and concise group of tags. 240 tags for 10,000 books.
