Comment (by RJVB):

 Craig, I think you hit paydirt by a more specific requirement than usual.
 You'd need

 {{{
 qt5.depends_component \
     qtscript \
     qtwebkit \
     mysql-plugin

 if {[variant_isset qt5kde]} {
    register_active_variants qt5-kde mariadb55 mysql55
 } else {
    register_active_variants qt5-mysql-plugin mariadb55 mysql55
 }
 }}}

 the extra complexity is because qt5-kde-mysql-plugin is a stub port for
 something provided by qt5-kde itself. Even if the stub was added to the
 dep. list I'm not sure that requiring it to have to indicated variants
 would have the intended effect.

 It is not yet clear if `[variant_isset qt5kde]` will be the preferred
 check for dependents, or `[tbool qt5.using_kde]`.
