GitHub has that too, I noticed the other day. I still think Gitlab is much better, and use it by default for everything new, but fair's fair :P
I love the integrated CI, though, and the use cases it enables. I love that I can just make a pipeline that lints, tests and compiles my code and then, if all of those pass, ends with deploying it to production.
There are many more Gitlab features I like a lot, and the fact that they're all integrated is icing on the cake.
It took forever for GitHub to get anything, until Gitlab lit a fire under their ass. GitHub were perfectly content just resting on their laurels while every essential feature was handled by a different $15/mo third party service.
