OS/2 fsSelection useTypoMetrics

I've recently been learning more about the OS/2 fsSelection useTypoMetrics flag and was wondering how commonly type designers set that flag in your fonts. Do you set it in your fonts? Or purposefully not? 

For those unfamiliar, the useTypoMetrics flag indicates to DirectWrite to use the sTypo metrics values instead of the usWin metrics values for display of fonts.

Thanks!
