Description
I'll repeat the comment I left in LU-5834
While it's ironic that it was a member of the HYD team that originally requested this change, I wonder if it's really the behaviour we (the royal we, not the HYD we) desire.
It seems like a good idea on the face of it, but it has undesirable side-effects in certain use cases.
If one has both the server and client repositories configured and enabled on a node and one tries to install lustre-client one gets this behaviour:

This is clearly not what we want to happen. As you can see, the lustre-client package which is what we really wanted is obsoleted by lustre-dkms
If we do a little bit of cajoling, we can get what we want:

But this really does not feel like the element of least surprise.
A lesser surprise to me would be for the installation of the client to just fail with an error that it conflicts with the server such that the admin realises he needs to remove the server first and then install the client.
