backward compatibility and (!) gives forward compatibility too:

backward compatibility
    If someone decides to put config files in /usr/lib/sasl2/ and never even
    bothers to put things in /etc/sasl/ things stay as they have always been.

forward compatibility
    If someone decides to use /etc/sasl/ things work - even if legacy config
    files "hang around" in /usr/lib/sasl2/.

Both work. If /usr/lib/sasl2/ always overrides settings in /etc/sasl/ only
/usr/lib/sasl2/ works reliably.
