Where should it go?

Just like the gitlab-ci.yml, it handles things related to the whole repo, it basically runs a script in the root of the repo anyway.

Sure, supporting other paths is useful (eg. in case of a monorepo), but this default seems sane. Though I'm interested in where others move it, and why.

it's pretty common to have a .ci folder for your build scripts.

But nothing is fundamentally wrong either with XDG-esque directory structures.

.config/travis/

.ci/travis/

all the same to me, as long as it's consistent.
