 I do not speak for upstream.
 I would guess that (if they care at all) upstream would be happy to
have you use different NEVRAs, and certainly wouldn't go out of their
way to choose NEVRAs that are the same.

 Certainly it seems like you should be pretty safe if you did something

 Upstream: foo-1.2.4-8.el7
   CentOS: foo-1.2.4-8.el7_0.0c1
   CentOS: foo-1.2.4-8.el7_0.0c2

 Upstream: foo-1.2.4-8.el7_0.1
   CentOS: foo-1.2.4-8.el7_0.1_0.0c1
   CentOS: foo-1.2.4-8.el7_0.1_0.0c2

...and that should provide the same level of "upgrade compatibility" you
have now (every CentOS build would upgrade to the next upstream build).
