I feel this is a trend now with new projects, it's also the case in Node.js, Go and new Python packages.

This can go as absurd as the package named "a" in npm (https://www.npmjs.org/package/a) which is used by a lot other packages. I also had some trouble to figure out what each package is suppose to do when using RoR.

However, I would not say it's necessary easier in older languages when I see the amount of weird acronyms used in the Java world.

Ruby does this too. Thor, God, bluepill, and pony all come to mind.
