As I spent a lot of time figuring out what happens in nuxt/nuxt#10139, I would like to see watchParam menitioned on https://nuxtjs.org/docs/components-glossary/key#the-key-property because that is how one can get watchParam effect.
Also I think it would be good idea to explicitly menition when data() is called in https://nuxtjs.org/docs/concepts/nuxt-lifecycle#nuxt-lifecycle

@Uzere, Actually agree with you, unfortunately, I have no experience in graphic design and will not be able to update hooks.
Also i test behaviour when set watchParam: false and changed param and query, by source code i think this have bug and if true, this needs to be added to the documentation
UPD: If i set watchParam: false, watchQuery: true and change param AND query of route, nothing happens. Tests for it
