Why is FreeBSD still so far back?

Nope, the behavior is correct. OFMT is still used when converting
values for `print', while CONVFMT is only for number to string conversion.

Your use of `+' forces gawk to convert "" to 0.  That number is
added to the numeric value of 1/3, which is converted by OFMT for printing.
Using straight string concatenation will get you what you want:

        $ gawk 'BEGIN { CONVFMT="%.2f" ; print (1/3)""
        > a[1/3]=1 ; for(i in a)print i}'
        0.33
        0.33

HTH,
