I considered that at first but there are a lot of long title series that don’t fall under the isekai umbrella, while the isekais that fall under the shounen umbrella tend to still have the shorter titles.
It just so happens that most isekai fall under the shoujo/ecchi/comedy umbrella, hence the large amount of overlap. So while there’s definitely an association, I wouldn’t necessarily consider it an isekai thing specifically.

afaik a lot of recent mangas & anime started out as web novels.
the popular sites at the time didnt have subtitles or descriptions, so authors worked arround that by putting a description in the title field.
as far as i have heard those sites now have subtitles and descriptions,
so this should be a temporary trend
