IIRC explicit drops aren't even honored any longer...
They are, they always have been. Drop a temp table and you can't access it any longer. Essential when testing code before putting into a procedure. 'cannot create #test because it already exists' is annoying.
Now, the engine may choose to cache that temp table (strip out the metadata and just leave a couple of allocated pages), but it can do that with automatic drops on session close anyway.
