First, very valid concern regarding table name.

> Other than saving some typing,

I would like to point out the corectness aspect of the proposal.

Today foreign keys are enforced during inserts, updates, deletes. (you just can't violate fk. this is so good) But you can violate it in selects. (e.g. mistype column name, forget to include a column)

This proposal (or its adjustment) would allow to use fk also during select. It's like static typing for join conditions.
