I've been trying to keep tag types organized with an encoding that hints if a tag uses its id field for file ids. However this seem to have been a mistake. Using a null id of 0x3ff greatly simplified quite a bit of the logic around managing file related tags. The downside is one less id we can use, but if we look at the encoding cost, donating one full bit costs us 2^9 id permutations vs 1 id permutation. So even if we had a perfect encoding it's in our favor to use a null id. The cost of null ids is code size, but with the complexity around figuring out if a type used it's id or not it just works out better to use a null id.
