Lofree / Kailh POM Shadow switches

Does anyone know if the new Kailh POM low-profile Shadow switches are available to buy anywhere? My guess is “not yet”, because they were designed for the Lofree Flow which is currently in the process of shipping to its Kickstarter backers Lofree Flow

What struck me about the Shadow switches is the upper housing appears to have less of a shoulder than the Choc v2, which I guess would improve its compatibility with MX keycaps. Best visual comparison I have found so far is at 全球首款全POM矮轴!凯华Kailh x Lofree洛斐联名推出—影系列。-腾讯新闻
