If you saw the descriptive picture posted further up you would see that there is no difference in HDD space taken between 'split' or 'merged' modes. Also I would expect those people that try to collect all ROMs would prefer 'merged' mode for *less* number of .zip files required.
I am not a full set 'collector' and I prefer 'split' mode.
'non-merged' is a waste of space unless you were refering to wanting to be able to run 'clones' but not 'parents'.
Also, most of this discussion is about the questions clrmamepro asks of the user when creating a new profile. It is not automated so there are no 'defaults', but maybe in the future? (but the question then is to what)
