<p class="MsoNormal">> You are correct and this seems to be an error. I don’t think in the earlier ML thread[1] that anyone remembered that the quota classes were being used for default quotas. IMO we need to revert this removal as we (accidentally) removed
a Havana feature with no notification to the community. I’ve reactivated a bug[2] and marked it critical.<br>

+1.<br>

We rely on this to set the default quotas in our cloud.<u></u><u></u></p>

<p class="MsoNormal">Can you elaborate on this point. Do you actually use the full quota-class functionality that allows for quota classes, if so what provides the quota classes? If you only use this for setting the default quotas, why do you prefer the API
