There is no "of course" about it. It may be true in your case, or even
many cases, but not all, and buildbot needs to support those.

The branch isn't actually what buildbot refers to as a property. It is
rather a source-stamp attribute (of which a build will have one for each
codebase).

They can be accessed using `Interpolate('%(src:<codebase>:<attribute>)s')`.

As mentioned above, `branch` isn't actually a property, so can't be set
with `set_properties`. Instead, you can control is with `sourceStamp`,
as documented here:
