It’s not an extreme way at all. I was thinking along the lines like testing in a virtual machine in example. Also one does not have to switch whole distribution each time they try. Installing a distribution is often easier than installing the tiling window manager and configuring it hours and hours, finding out details how to do stuff, to get it into a state that is comparable and styled the same way as the other distribution spins.

This dos not mean one has to use that, you are still free to install and configure it from scratch. Some distributions have it and its great.
