+1 coming from a university setting. I think this is very typical
amongst my peers. Not "good" , or "desirable"; but just a fact.

I also suspect this is a "size of the cluster" issue. Many of the
HPC-clusters I see are "small". 30-50 servers clustered together. I
think these tend to be a lot more messy and hacked-together than the
nice, clean, efficient setups  many of you on this list might have.
Mark probably deals with "huge" systems. Just a thought.
