That’s an interesting question!
I have not seen the <title> tag being used in the OPF file; usually, <dc:title> is nested within the <metadata> tags in the OPF. For all content files, the <title> tag is used to describe the content of the document.
Since the OPF file is not a content file and is not read aloud by assistive technology, it doesn’t need a <title> tag. The OPF file tells reading systems how to organize and display the contents of the EPUB, and transfers metadata to e-reading devices and other software.
