You've got the interop right.

Unfortunately, Intel is no longer doing public maintenance versions of Lustre, so 2.8 will not receive updates after release.

So if I understand correctly one has the following "centos options":

1. Lustre-2.5.3 with CentOS-6 on both clients and servers.
2. Lustre-2.5.3, CentOS-6 on servers, and 2.7.0 and CentOS-7 on clients.
3. Wait a while and use Lustre-2.8.0/CentOS-7 on clients and servers.

At least on clients I would prefer to run CentOS-7, but if 2.7 (and 2.8 - will this version receive updates?) are less reliable that might not be a good idea?

Any thoughts on this would be greatly appreciated.

No - 2.5 is the last public stable client release from Intel.
