Just because the Java plugin is rarely used doesn't mean it isn't installed. Most PCs I see have Java installed, whether bundled by the OEM or some third-party piece of software, and Java always installs its plugin.
Stat Owl reports that the Java plugin is installed on 68% of browsers[0] based on data from 28 million monthly uniques[1].
