Good question. The main reason it loads all the time is shortcodes. bbPress doesn’t have any way to know that the_content contains a shortcode when the head of the page is being processed, so including it all the time is the safest bet for most people.

If you want to dial in your installation, you can wrap the CSS enqueue in a is_bbpress() check. is_bbpress() returns true when WordPress is loading up a bbPress specific page.
