Converting from RHEL to CentOS only makes sense on older, semi-retired machines.

why do you say that?
I say it because changing distributions is a major update and could break your system. You are taking the system off Red Hat support, which I require for critical systems. Also, supporting Red Hat is a good thing and helps all Linux.
I know it's good for me as a contractor because not having a smooth upgrade path available for free makes me more money that 'apt-get update'
Good for linux as a whole is debatable (not interested in doing so, just think acknowledging it is good)
