Water Buckets Evaporate upon Entering Nether

So, I was watching ibxtoycat on Youtube, and spotted a bucket of water in his hotbar. Now, don't get me wrong, I agree with him; Carrying a bucket of water everywhere IS a great idea... Unless it's the Nether. In the nether, when you place Sponges, they dry out. If you place water, it evaporates. Why not just dry this stuff out in item/inventory form? For instance, I could put a Dropper filled with Wet Sponges, facing down (with a 2-block gap) to a Hopper, with blocks ensuring no item lossage. If I were to automatically shoot the Wet Sponge items into the hopper, they won't dry. It'd be cool to make an automatic sponge-dryer with this mechanic. But, again, to balance this out (somewhat), it'd evaporate your Water Buckets, leaving a plain bucket in its place.

Now, onto the specifics (no code, although)

For players coming into the Nether (via portal, of course) with Wet Sponges or Water Buckets in their inventories, the Sponges and Buckets would be replaced with dry Buckets and Dry Sponges.

For Items, any item coming through a portal will instantaneously be transmuted to its dry form.

Thanks for your time and consideration!
