    Hi,

    When running Google PageSpeed, I am getting following warning
    “Avoid serving legacy JavaScript to modern browsers” which may allow me to save another 200ms.

    The bits of code PageSpeed complains about are in Wp Meteor script:
    Object.defineProperty
    Object.defineProperties

    Is it possible to add an option to disable legacy browser support and conditionally remove this code from JavaScript?

    Thanks,
    Rudolf
