Sadly while using a colon to separate the title and subtitle is common usage, I can't find any standard that specifies that usage.

Opinionated? I have seldom thought of a computer program as being able to be opinionated.

I just went through my library. Of 17,142 books, I have 113 with subtitles so ~.66%. Oddly, I found exactly 11 where the ePub3 standard for a subtitle was used:

Code:

    <dc:title id="t2">2019 Edition Fully Revised and Updated</dc:title>
    <meta refines="#t2" property="title-type">subtitle</meta>

Code:

    <dc:title id="subtitle">A History of Computer Entertainment</dc:title>
    <meta refines="#subtitle" property="title-type">subtitle</meta>

Oddly, for 9 of those, I added that metadata element when editing in Sigil.
