Contributing my 👍 even though we paired on this. The git rev-list --max-count=1 parameter is understood for Git versions in at least the last 15 years.
We've seen that this speeds up the command significantly even when there is only one result, as long as that result is in the recent history. Git keeps looking for more versions even when the file disappears (since it was added recently).

getFileAddedHashgets all commits that changed the given path and then discards all but the first result. By using--max-count=1we can avoid getting more commits than necessary. This can lead to significant performance improvements in large repos.
