rewrite rules flushing too often

With version 5.7 there is a flush_rewrite_rules() added in bps-directory.php:67, which seems to run on every page request. This is adds some high load to our database, because its updating the rewrite rules in database on every request.

As far as i understand, flushing should only happen on plugin activation and/or plugin update or if something changed, but not on every request.

Can you please do something about it?
