This is deliberate; the bumblebee package installs
/etc/modprobe.d/bumblebee.conf which blacklists both nvidia and
nouveau (in order to ensure that bbswitch gets loaded first).

No, not unless you expect the user to do manual configuration
(although to be fair, there's currently still some amount of manual
configuration to be done by the user before "optirun" works seamlessly
from the end-user POV, e.g. adding the user to the bumblebee group).
