Granted. I myself have just a few e-books showing subtitles. But I have e-books from various authors and different publishers using all the same title (I guess originality is out these days
). In those cases it is handy to differentiate with the subtitle (which amazingly all those books have also).

Indeed. But as some subtitles can be meaningful, they are now present only in the calibre database and not inside the e-book itself: hence they can get lost.
Further, I did found about 78 EPUB3-ish books in my collection, of which only 2 did use the subtitle element. One in the .opf file as follows:
Code:
<metadata ...>
<dc:title id="maintitle">The Title</dc:title>
<dc:title id="subtitle">An Interesting Subtitle</dc:title>
. . .
<meta property="title-type" refines="#maintitle">main</meta>
<meta property="display-seq" refines="#maintitle">1</meta>
<meta property="title-type" refines="#subtitle">subtitle</meta>
<meta property="display-seq" refines="#subtitle">2</meta>
. . .
</metadata>
and one in the HTML file:
Code:
<div epub:type="fulltitle">
<h1 class="BookTitle" epub:type="title" lang="en">Main Title</h1>
<h2 class="BookSubTitle" epub:type="subtitle" lang="en" role="doc-subtitle">An Interesting Subtitle</h2>
</div>
So indeed, usage and adding of subtitles seems very rare and probably not worth the effort.
