It can also be argued that on Windows it is more common to launch the application from a shortcut in the Start menu, on the Desktop, or in the launch bar.
I get that this is a change from the previous behaviour so some adjustments need to be made, but how bad is it really? 
The JDK has always had a bin directory and many other applications follow this pattern on Windows as well.

Making it configurable makes the most sense. But it may get complicated as the launcher exe needs to find the .cfg file without any additional info. Maybe the relative path to the .cfg file can be injected into the exe at build time, much like customizing the exe’s icon?
