The hacky method is

addItemInventory(256, -1)

i.e. add a negative amount. This was reported to work.
(replace 256 with the ID of the item you want removed)

I thought I tried this but didn't work but I'll try again.

I wanted to get rid of a specific item not in a specific slot.

It did work, but the item still looks like it is in the inventory until the world is reloaded.

Soon addItemInventory will be replaced with Player.setInventorySlot(slot, id, amount, data);

In which case you could do

Player.setInventorySlot(0, 7, Player.getInventorySlotCount(0) - 1, 0);

Could remove 1 bedrock from slot 0.
