it feels very weird to me that simply querying for the path would have side effects

Well, it helps to view it as a "lazy" repo - the code simply ensures that the path can be queried correctly.
If viewed this way, it's not a "side effect" but a necessary implementation detail.
Another way to do this is to add the call to #add_to_sparse_checkout everywhere the path is being queried, but that increases the risk of bugs. My proposition seems more robust to me.

This year, git and GitHub have added support for sparse checkouts and partial clones.
This PR adds support for these features in the spec repos. If a spec repo is added as a sparse checkout, (addition is handled in CocoaPods#10069), only the pods the user requests are fetched/checked out.
