I've removed the plaster from a lath & plaster ceiling in order to have the ceiling boarded with plasterboard and then platered.The laths on the ceiling remain in place and are holding up the loft insulation i.e. the laths are stopping the loft insulation from falling down into the bedroom.
I had thought about just putting the plasterboard over the laths, but now I've looked at the laths there are many, many nails since the laths are narrow and are close together. Consequently perhaps it may be a bit 'hit & miss' when attempting to screw the boards to the ceiling i.e. hitting the many nails.
Perhaps it would be better to remove the laths/nails to allow the boards to be easily screwed onto the joists, but how to keep the insulation up? Perhaps stapling some sort of strapping onto the joists every foot or so to keep it up until the boards are put up?
