Thanks for asking!

The approach I suggested is better for code readability (Single Responsibility 
Principle - `CoordCommandUtils` does way too much also in the moment) and 
testability.

I recommend reading Misko Hevery's testability blog, here is [the 
article](http://misko.hevery.com/code-reviewers-guide/flaw-brittle-global-state-singletons/)
 why we should use as little `static` methods as possible
