RedHat is specifically targeted to government and enterprise. They would be aware of that.
A better example is a user I should be able to install python 3.7 and use it, even if the system libraries for the core packaging is based on python 2.x. Traditionally most users would just build their system scripts on python 2.x (because it is there), which means that if you upgrade the distro from RHEL X to RHEL Y (which brings a python 3.x) you break a user's environment. This was a constant problem when you were trying to go through the RHEL 5-6-7 upgrade paths among other things.
It hopefully will be resolving the issues of people and packaged software using weird old versions because it is there and breaking when something changes. My favourite example is having to write in ancient bash just to support MacOS which still ships bash 3 something.
In a shorter version, the interpreters are still there and buried, just not on $PATH and given to the user as a what they should use.
(This is opinion based on how I have seen people abuse systems and try to upgrade them over the years).
