Template version number updating?

[GavinS]

Hi, 

The Developers' Guide says:

> Every template shipped with Bugzilla has a version number on the first
> line such as 1.0 at bugzilla.org. You should update this when you edit a
> template.
>
> You need to increment the major part if your updates make the
> interface to this template incompatible with the interface of
> previous versions. Otherwise, you need to increment the minor part.

This doesn't seem to be happening to templates at the moment. Should
it be, or should the guide be updated?
