mタグに寄せるとリレー実装に手いれない限り、jsだけホストするみたいなのが難しくなる
kindに寄せるとそれ以外のファイルを扱えなくなる
なので、両方使う方がいいのかなあっていう
Discussion
Maybe having a "resource" kind and just using it as storage, a CSS, JS or JSON file is understood by the content and how you link it, there's no real need to have dozens of types, at most a tag with the content-type to simplify and scale freely.
There is no need to differentiate "kind" if you are using regular web hosting. However, there may be cases where you want to host only HTML for exploration or share only JavaScript for code sharing. But in the current relay implementation, it is not possible to restrict inserts based on the value of the "m" tag. Therefore, to implement relays like the ones mentioned earlier, you would need to either develop custom middleware or modify the relay. Hostr aims to provide diversity without altering existing implementations as much as possible, which is why this specification is in place.
