   Not actually a new one, but a the message itself has been updated and
the condition cleaned up a bit so it might catch more error cases than

   Before this check was only done when defining a project id using the
'use-project' rule, but not when doing it using the 'project' rule.

   All project id's live in a single namespace and I can not think of a
reason why anyone would absolutely need to change one id to map to a
different project than it already does. Any target references using that
project id would then be in danger of being interpretted incorrectly.

   On the other hand, if you do see a reason why the old behaviour was
'desireable', I'll gladly update the code as needed.

   Hope this helps.
