There is a difference here. In the case of user name it is redundant information
denomralized for the sake of performance. For title, it reflects the current one
used, so it is not redundancy per se.

More complexity in the code, plus hardcodes special meanings which
we have today.

It does not save much storage since we are talking of an additional int
per row.

Moreover, it would be hard or complex to select on a bit in the field,
which is not a good database practice.
