Relevant to the above, it feels like you could make spec out of malli but not the other way around

There is more in the box for sure. On the other hand it's good that Spec does not have all that because it is in core

How much of that "in the box"-ness is just about having a single maven artifact and how much is actual interdependency though?

At least in theory we could just have the schema introspection and everything else could use that and live in separate jars

But currently there is a monolithic schema protocol which does set a lower bound on the box size

See also https://clojure.atlassian.net/browse/CLJ-2251 but I recall Tommi saying that walking Specs would still be janky

There is spec/visitor in spec-tools @nilern. I think that the real problem is that it's impossible to decode serialized specs in runtime.

You can go only one way without a proper way to reverse

Yes the ticket mentions spec-tools and various details that I know little about since i never touched spec-tools
