Anyone using SpecialAnnouncement markup?

Google recently announced support for the SpecialAnnouncement markup schema. It's mostly for Covid-19 related announcements but this is BHW Anyone experimented with this yet?

Be aware, that using schema wrongly could seriously affect your ranking. People think that schema is useful to trick users into an improved snippet that gets the attention easier, but it also introduces some extra metadata that can switch your site intent to a different intent: for example, an article to a product or an article to an event.

Consider that, if the search intent is article research, and your schema is clearly showing product or event info, you could be deranked without warnings in GSC or anything like that.

Tested with 2 clients and one of my sites.

I normally avoid playing with schemas, I had tried the question one and each and every url got error, hence I only keep the basic schemas on
