Thanks. That works with my MWE, but in my document I actually have
a chapter, and chapters start on the right page, even if I add page=no
to \setuppagenumbering:

    \setuppagenumbering[alternative=doublesided,page=no]
    \definemakeup[ToC][align=middle,pagestate=start,doublesided=no]
    \starttext
    \startfrontmatter
      \startmakeup[ToC]
        \placecontent
      \stopmakeup
      \chapter{Preface}
    \stopfrontmatter
    \startbodymatter
      \dorecurse{10}{\chapter{Foo}}
    \stopbodymatter
    \stoptext

I have no idea how to allow chapters to start at arbitrary pages when
alternative=doublesided.
