A loft space should have adequate capacity for moderate storage of goods.
What appears to have happened with the plaster ceiling is the installation due do hammering has displaced the plaster.
In your loft space do you see the tiles? If this is the case you have no sarking felt, you may have a long term problem with storage of paper, as it will absorb moisture and your books will deteriorate over time.
It is a pity your builder removed the insulation as this will reduce the thermal performance of your property. You can consider boarding out the rafter and place a rigid insulation and plasterboard to reinstate the thermal performance.

Hi there,
The plugs on your ceiling are the heads of the screws/nails holding the plasterboard, they are showing up because of the vibration/weight now or during the work.
It is always infinitly better to fit some timbers 3/2 or even 2/2 (if headroom is a problem) ACCROSS the existing floor joists to create a frame and to spread the load of the chipboard and the stored items (this way you can even leave the second layer of rockwool insulation as there is enough space).
The new timber frame should touch every single existing joist (put wedges if there are not level)so that the weight is spread accross the floor rather than being on ONE joist.
Books are heavy so the builder should have known or at least he should have warned you about possible cracks/plugs in ceilings etc.
I always tell the customer the above if they insist on not having a frame accross.
