Both of these have nothing to do with Modularity, and can be done with
They have everything to do with Modularity, because that layer is
where that stuff was implemented. Modularity was the result of the
efforts involved with Factory 2.0, which gave us a lot of improvements
in our build infrastructure tooling for the first time since 2007.
Most of that rolled out in 2017, a full ten years after the last
revamp of our infrastructure.

Modularity doesn't support installing multiple versions of the same software.
It's one of the key issues with the tech.
Modules can be designed to be parallel installable if the underlying
software natively supports that. For example, Python works that way
now, and thus in RHEL there are parallel versions of Python shipped as
modules. It doesn't change the nature of the software.
But it makes it easier to make multiple complete, yet conflicting,
collections of a language stack.
