WordPress renames slug of tags used in multiple taxonomies?

I’ve noticed WordPress renames the slug of identical tags used across multiple taxonomies, is there an easy way to change this behavior?

Let’s say I create a tag called Nintendo under the publisher taxonomy, then also create a Nintendo tag under the developer taxonomy. WordPress will prefix the slug of the second tag with a 2.

This basically makes the taxonomy/tag system unusable for my application. I want the slugs to stay the same across multiple taxonomies.

Found out why, slug column has a UNIQUE index. Looks like I’m just going to have to code my own script to handle the publisher/developer relations if I want a consistent URL structure. Thought WP was more flexible than this, oh well :/
