[Plugin: Posts 2 Posts] p2p_init vs wp_loaded

I am building a plugin that registers user definable custom post types (defined as part of the plugin setup). I’d like to make sure I am controlling the correct order in which my post types, taxonomies and p2p relations are set up.

So I’ve been using wp_loaded to register p2p connections. I’ve not had a chance to check your code, but I’m guessing that you hook into init to invoke p2p_init?

Do you foresee any problems with me using wp_loaded?
