BuddyPress will soon be improving the way it loads its JavaScript and CSS assets so that they are only loaded on community pages. Previously, the plugin would load them indiscriminately on every page.
BuddyPress lead developer Mathieu Viet said he’s not sure there is a specific reason explaining why this was kept in place. Before the plugin introduced the BP Theme Compat API in version 1.7, it was necessary to use a BuddyPress compatible theme like the one bundled by default (BP Default).
“I think we kept the way this theme was loading these assets into the first Template Pack (BP Legacy) we added to BuddyPress,” Viet said.
