Better way to create a "soft depend"?

[jan64]

You can do something like hooks, by allowing other plugins to register their handlers like it's done in IRChat.
This requires the library plugin to be loaded before others.
(Is the case when not all plugins are loaded at the same time really important? It seems like a bit of an overkill to me with our current API.)
