I would like to avoid steering us in a world where we are required to
explicitly mark registry entries as extensible. Instead, registry
entries should simply assumed to be extensible. Just like we assume that
XML elements are extensible in XMPP, and for that reason also do not
explicitly declare that extensibility in your XML schemas (minus a few
exceptions).

Otherwise, we would need to perform this over and over again for every
add-on XEP that deals with elements that are part of a registry, for no
reason. There is *no* advantage in explicit stating it: Just as on the
protocol level, either the extended additional information was
negotiated, and you are prepared for it, or you are not required to
understand it, and can simply ignore it while processing the registry entry.
