> That could impose a significant performance and drive space penalty in the event that substitute drive paths are changed, but I would expect such changes to be rare.

I think the more likely case is that one would build their repo under the substitute drive and later build it under the expanded path on the original drive. Though I feel like a lot of caching might then break.
