It's done so that you can have multiple versions of the tools installed
side-by-side rather than being blindsided by upgrades breaking your
toolchain.  This is rather the same justification that the Python community
uses for its similarly weird way of selecting from side-by-side Python
installations.

As someone working to produce regulated environments (to ICH-GxP), this
makes sense to me.  As someone who has to use both day-to-day, it's a royal
pain in the neck!

Cheers,
