You will not be able to use any of the taxonomy functions, such as
get_terms() or do taxonomy queries using WP_Query.

And why wasn't WordPress code & db structure implemented in a way so that

We could store all those options as a serialized array in the wp_options
table, but there's really no point, since we don't have any UI for
registering taxonomies from wp-admin.
