Comment (by nacin):

 I can't find my previous answer on this subject (may have been a ticket,
 but can't find it) — but basically, we deliberately don't restrict post
 types for compatibility reasons. Some were using the post_type field well
 before register_post_type() existed, and even then, it doesn't ''need'' to
 be an error condition. Most of WordPress won't recognize the post type,
 but wp_insert_post() is a low-level API (it's also a high-level API; yes,
 it's a problem) and doesn't care.

 Adding an error now will likely cause other problems. I could picture a
 situation where someone is registering a post type, but somehow does so
 (at least in some situations) after a wp_insert_post() call.
