I posted my comment because the linked proposal itself never uses the abbreviation "KYC" and none of the early comments spelled it out, so if (like me) you didn't already know what it means a quick Ctrl-F wouldn't help.
The proposal seems to use the term Customer Identification Program (CIP) instead, mentioning KYC (spelled out) only once, in the introduction:
> Section 1 of E.O. 13984 requires the Secretary to propose, for notice and comment, regulations that mandate that U.S. IaaS providers verify the identity of foreign persons that sign up for or maintain accounts that access or utilize U.S. IaaS providers' IaaS products or services (Accounts or Account)—that is, a know-your-customer program or Customer Identification Program (CIP).
