Comment:
Hello. I would like to point out something else. As Dune is invoked with `--profile=release`, this deprecation warning (OCaml calls it an "alert") [should be non-fatal](https://dune.readthedocs.io/en/stable/faq.html#how-to-make-warnings-non-fatal).

The real problem should be this:
```
File "src/support/json.ml", line 3, characters 9-26:
3 | type t = Yojson.Basic.json
             ^^^^^^^^^^^^^^^^^
Error: Unbound type constructor Yojson.Basic.json
```

There's a commit in the 0install repo that seems to address this issue: https://github.com/0install/0install/commit/70b6047.

However, that commit doesn't seem to be included in the latest [v2.3.15](https://github.com/0install/0install/commits/v2.3.15) release, so this issue will very likely need a patch to fix.
