Just noticed that David Bruant already proposed Object.prototype.toPropertyDescriptor for this exact same reason in https://mail.mozilla.org/pipermail/es-discuss/2011-May/013971.html, apologies. I think it is better as a static (class) method since it is reflection-related, and to avoid attackers from defining a bogus "toPropertyDescriptor" method on property descriptors.
