Mithril has been around for 7 years. How old does it need to be before it's not "the new hotness"? Just because you haven't heard of something doesn't mean it's new, and it would behoove you to not immediately dismiss things that are new to you as things that are new in general.
Your heuristic that a large ecosystem is what makes a framework good precludes you from ever again touching any new project. It's a short-sighted approach.
At some point, you have to grow up as a developer and try to understand the real world problems that modern declarative web frameworks have solved. I stated that mithril will be my tool of choice for hopefully 20+ years, so your framing this as me getting lost in the new hotness doesn't even hold up. This is about real tools, which are useful today and tomorrow, and which have slow API churn to facilitate longevity. It's just a bonus that mithril is also faster and far more terse than React and friends.
