One of the most important countermeasures against credential abuse is the ability to ban users who behave badly. This sort of revocation happens all the time on real sites: for example, when a user posts spam on a website, or abuses the site’s terms of service. Yet implementing revocation with anonymous credentials seems implicitly difficult. In a non-anonymous credential system we simply identify the user and add them to a banlist. But anonymous credential users are anonymous! How do you ban a user who doesn’t have to identify themselves?
The biggest compromise appears to be in memory, though. While Apple doesn't include it in the main body of its press release, but when you go to preorder the device, it appears to only come with 8 GB of unified memory, without an option to upgrade. You do get the option of either 256 GB or 512 GB of storage, which only costs $100 more.

于先生说，近10年来，国家、相关行业陆续颁发了许多无障碍标准和图集，不同标准互为补充。但有的设计单位、施工企业、监理单位，对施工及验收标准不熟悉甚至不了解。与此同时，“无障碍设施分散于建筑工程的各分部分项工程中，分类较为复杂，加上无障碍设施在专业工程中所占份额小，在施工方案中通常不会对其进行专门阐述。要求也不明晰，在施工及验收中常常得不到应有重视。”于先生说。
