<p class="MsoNormal">“<span style="font-size:12.0pt;font-family:"Segoe UI",sans-serif;color:#171717;background:white">The OpenType Layout feature model provides great flexibility to font developers because features do not have to be predefined by Microsoft
Corporation. Instead, font developers can work with application developers to determine useful features for fonts, add such features to OpenType Layout fonts, and enable client applications to support such features.</span>”<o:p></o:p></p>

<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I’m not sure if the intent was that MS felt free to reject features they didn’t like, or simply that they would maintain some minimal quality bars and not take things that were clearly not well-formed or supportable (e.g., no world-peace
feature).<o:p></o:p></p>

<p>That's a not unreasonable interpretation of the way a registry could or should work, but so far as I know there is no formal statement to that effect, particularly with regard to the registry of OTL features (and script tags, and language system tags, and
variation axis tags) as maintained by Microsoft.<o:p></o:p></p>
