For the true pure "EEE" experience. they would need to be pushing us back towards some other MS product.
Embrace git. Extend git. Extinguish git. Everyone is tired of git and just goes to Microsoft VSCode Repos.
With "gh" in theory they could do that: get everyone using a custom tool... and while no one is paying attention, change out the backing infrastructure to use MS Repos Tool. And you wont even notice because gh was built to make the transition seamless. (I doubt this is truly the case because there is a lot of automated tooling that uses git that would break in that case)
And now when you decide you want to pull your code off github to go to gitlab, it becomes too much of a hassle.
