what json-ld does, or what it allows you to do, is explicitly declare a `@context` that is equivalent to your "implicit context".
this works fine if there is only one declaration that is shared exactly between two parties, but it gets complicated when the "implicit context" differs or isn't an exact match.
this means that there cannot ever be a singular #fediverse network, because the "implicit context" differs between each software project. the only guaranteed overlap is the AS2 one.
