I recall that this became a big problem for the Homebrew project in terms of load on the repo, to the extent that Github asked them not to recommend/default-enable shallow clones for their users: https://github.com/Homebrew/brew/issues/15497#issuecomment-1...

This is likely to be lower traffic, and the history should (?) scale only linearly with new data, so likely not the worst thing. But it's something to be cognizant of when using SCM software in unexpected ways!
