  The point is that there are many configuration files, each of which can be hundreds of lines of text.  "I added stuff" tells me nothing.  Where did you add it?  Which file?  Where in the file?

Having it switch to camel case with a dash wasn't clicking.

  Or use the same name?  I don't know of any programming language where you can change case of variable names, *and* change dashes to underscores, and it will just "do the right thing".

  Yup.  Technical details matter.
