I have looked over the changelog and searched in the forums for this and haven't found anything about it yet. I think it would be useful for automation to have pumps accept glass bottles and pump water in to them. Would allow for easier production of potions. It allows one to for example have fire resistance potions in the nether with a lappack and still not get overly damaged while taking your q-chestplate off. And night vision potions would still be useful for swimming under water with a q-helmet. Shouldn't be a total pain to code either. Just check that the pump is pumping water and allow to accept glass bottles and output water filled bottles.
Thanks,
