In my case I think the defaults are good. (But I do not know how I
will use the function in the future. ;-) ) But I want to share it on
GitHub and it would be possible that for someone else my defaults are
not correct and then it is nice when they can be overridden.

I do not see myself doing this, but I like to know ‘everything’. When
I have a program with two different modules that both import this,
they would get in each-others way? How?
