	- Use the forked [binding](https://code.forgejo.org/go-chi/binding) library. This library has two benefits, it removes the usage of `github.com/goccy/go-json` (has no benefit as the minimo library is also using it). It adds the `TrimSpace` feature, which will during the binding part trim the spaces around the value it got from the form, this is done before validation.
