The only package or class with a ProvidesExpl which has not already
been accounted for is


The classes which rely on at least one package/other class with expl3
dependencies are


None of these declares themself as \ProvidesExplClass, nor do they
contain \ExplSyntaxOn.

Btw, the


is a kind of false positive. It contains \ExplSyntaxOn, but only to
temporarily disable it, in order to load the polyglossia package
without allowing it to load other packages, or to turn on
ExplSyntax. Its documentation says

    In the XeTeX case, we load polyglossia with a dirty trick to
    prevent it from calling fontspec.

but I can't really see why he needs to prevent ExplSyntax. In any
case, chextras itself does not use expl3.
