Turns out this is more complex than I initially assumed.

We can easily use adventure in Message. However, most messages are composed before passing them to Actor.sendMessage(String) (which calls Message internally). Here, composing takes place within the internationalisation handling in DynamicMessages. In particular, placeholders in strings are replaced using a java.text.MessageFormat instance which returns strings.

Here are the options:

1. Use adventure only when Message is called explicitly. Whenever placeholders are handled, these cannot use any of adventure's fancy formattings.
2. Overhaul DynamicMessages to return adventure chat components. However, we need to continue to use java.text.MessageFormat for placeholders (e.g. numbers or choice formats), while also return objects in place of some placeholders.
