in my case it's more often which audio, gamepad or graphics backend but yes, I actually had the log backend configuration request once ! (wanted to choose to log stuff in text files or websockets depending on the case, for a GUI app ; there was an explicit requirement that the entire software could be configured and used with only a mouse, no keyboard so many configuration menus were needed)
Literally every non-toy software I had to develop in my life required that lol
