[Yum] why does yum have to fail when one repository fails?

Is this a valid counter example?:

Lets say on that same day upstream released a security update which was 
_really_ important to ship to all machines. Lets then say that I had 
exclude=kernel in all the respository definitions apart from my local 
repository.

If yum did have "carry on if a repositroy is unavailable support" would 
the end result not be: all my machines would have the security update 
and would _not_ have the upstream kernel that I did not want?

.. or have I missed something?
