    Does this mean we should not modify this behavior because "this is what Oracle 
    does"?  I can envision where using currval() before nextval() can be useful.

    Actually, what you are proposing was initial behaviour of currval().
    This was changed to be more consistent with 1. & 2. (note - not only 1.,
    but 2. also).
    
    But personally I haven't objection against changing this again.
    Men, vote pls!
