Is it possbile to introduce `E^dedupe` for this?

I mean, change the defualt bahavior into DEDUPE_AUTO
(or DEDUPE_UNSPECIFIED) rather than DEDUPE_OFF.

If `--chunk-size` is specified, DEDUPE_AUTO will be
DEDUPE_ON, but `-E^dedupe` can disable it.

If `--chunk-size` is non-specified, DEDUPE_AUTO will
be DEDUPE_OFF instead.

see TIMESTAMP_UNSPECIFIED for an example,

Thanks,
