I'm skeptical that this would be of any performance benefit on the
kind of server most likely to host BuddyPress: something with opcode
caching and a decent amount of memory. Especially with a good number
of users, in which case the net result will be the same of loading all
the components into memory, but a result the server arrives at less
efficiently.
