Eg: I have my movies and actors custom post_types. To make the
relation I _mirrors_ actors (title + short description) to a custom
taxonomy actors_tax and then apply the right tax term(s) to each

It is not a hard but it is a tedious task. Well it is what it seemed
to me, a new WP developer.

Since WP 3.0 I had to use custom post_type and I needed relations
between them three times. Why? Because taxonomies are too basic: no
HTML description, no thumbnail, no ordering. How? Using post meta
because I didn't have the time to mess up writing a taxonomy mirroring

I am totally sure that many developers will need such post2post
relations too. So I think adding a mirrored_tax_id to custom post
types and have WP handle the mirroring is a neat feature I'll use a
lot, and I am sure others will too.

Anyway you are pointing to some interesting feature/functions I wasn't
aware of. Let me ask you about them in a separate thread.
