I come late to this topic, but from my very first lessons I learnt not to see f clef = LH and g clef = RH. Very often the way a score is written does not imply that the hands are distributed this or that way. My main concern is always to make sure the voices are not broken and that finger legato is assured. If this means dividing a voice between the hands, so be it. The aim is to play something well with the minimun risk of going wrong. At present I am practising a piece (4 parts) where at times one of the voices may go: LH LH RH LH RH RH LH and so on. All this to avoid as much as possible the use of the pedal.
