In reply to Peter.

I don't think it has to have BP-specific templates included in order to have basic BuddyPress compatibility (as in, the components look decent and not wonky when BP is activated). When I tested with BP, everything looked great. I don't think it's misleading to say it's BP compatible. I think as long as they use WP standard template loading approach, the could be labeled as compatible: https://wptavern.com/why-wordpress-theme-authors-still-need-to-specify-buddypress-compatibility
