I considered the case of changing passwords later in the answer. We get system which leaks some information about passwords if there are multiple leaks of database. Is it bad? Yes. Is it better than a single per-database salt? Yes. Is it worse than random salt? Of course.

comment Needing to encrypt plain sight information
@Andrew User1 can give away decrypted plaintext without revealing any keys anyway. Perhaps, you can tell us what kind of problem you're trying to solve?

Encrypt content with a randomly generated key. Encrypt this key for each user with a user-specific key.
