If it's an SV Unicorn, it can probably afford the "Data Center" enterprise offering. Though from comments here, even that may not be a smooth migration from the a la carte on prem products, depending on what add-ons they use...
Right, the change is fundamentally retiring the lower-priced single-node offering for small orgs. Likely their market understanding shows that organizations with sufficient motivation to stay away from the cloud are also mostly willing to use the higher-level Data Center offering. It's not only the same bits though, it add some extra enterprise-flavored features also.
