New Calendar List Template

What's the plan with the new Calendar List Template? It's modern look but not linked to Events, no fields, no explanation of its difference from events, no alternative Events list (which is poor but the best we have)...

How do I create an SPO Events list? I used to add an Events web part and click "add event;" now the link is disabled. The web part is configured to all events on the site (not a specific list). I can't even copy it from an existing list in another site.

There's a migrated SP2013 Events list on the site, but that didn't previously prevent the creation of a new one...
