IMO, this is not a good idea. You're coupling database schema with code
that's closer to display.

All access should be via an API into the C4:: or Koha:: namespace, and
the modules there are the only ones that know/care how the database is
actually laid out. This means that if we want to change how things are
stored[0], only one module needs to know about the change, and it can
still present the same interface to code.

The moment that you have more than one place talking to a fairly
low-level system like the database, you are going to have problems (e.g.
the issues in the current system where so many modules touch the account
code that refactoring it is a huge nightmare.)

[0] from fixing badly named columns/tables, to adding caching, to
refactoring the schema to make it more efficient, to not using the
database at all for some reason.
