<p class="MsoNormal">Office has a font service, serving fonts to (recent versions of) Office apps. My understanding is that they strip DSIG tables from fonts in the service. So, I would assume that recent versions of Office shouldn’t require DSIG tables to
enable features in Latin fonts, though I haven’t confirmed that.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">This is all product commentary: it can inform whether DSIG may still be relevant for fonts, though of course doesn’t belong in the spec itself.<o:p></o:p></p>

<p>In addition to triggering the OpenType icon, a DSIG was (is?) needed in older versions of Microsoft Word to process some OpenType features in Latin script fonts.<o:p></o:p></p>

<p>As recently as Office 2013 this was the case, and Office 2013 has not reached end of life yet.<o:p></o:p></p>
