NOUNREF option

I haven't experimented with this yet, but it occurs to me that with V7's
NOUNREF
option RPG will be doing much the same thing as SQL. Both have to have
access
to the base record buffer - the difference being that RPG has always
unloaded the
individual fields into their storage locations. With NOUNREF only those
fields that
are actually used will be retrieved.

Somehow, though I've been on 7.1 for a long time (and this was available on
6.1), I somehow missed this NOUNREF option.

Is there any downside to making NOUNREF the default? I have read you can't
debug a variable that's not used in the program if NOUNREF is specified,
but if the variable isn't used I'm not sure how often one would need to see
the value when it isn't even used . . .
