That's the approach I'm taking with the API: more asking, less telling.

And having a variable is not the best UI there is. Third-party project 
backends already have some ways to configure them, so we should just let 
them provide the information.

Projectile has .projectile which contains similar information: 
https://www.projectile.mx/en/latest/projects/#ignoring-files

EDE has Project.ede, although it doesn't seem to include the notion of 
ignores. ede-ignored-file-alist contains something pertinent, though 
(but that variable is weird).

More or less. Although doing that for just one file won't change much in 
the user experience.
