I think doing it through filters is too transient.
Activating/deactivating plugins could cause the IDs to shuffle.
Hardcoding the core taxonomies is fine for now, but what if we add
another core taxonomy down the road?  Its ID can't conflict with a
taxonomy ID that a plugin grabbed.  We could reserve a block of IDs
for use by core, I suppose.

Also, do we want to store some meta information for taxonomies.  For
example, a hierarchical flag that says whether the taxonomy can do
hierarchies.  For taxonomies that don't support hierarchies, we can
avoid running hierarchy specific code and queries in our generic terms
