\"Finding concurrency bugs seems to need the test repos to contain more files than the two or three\" -- it should be enough to run a concurrent operation many times on a small repo. This will test the different possible orders of operation. Most concurrency bugs only involve a conflict of two or three operations.
Running under something like https://rr-project.org/ can be used to reliably reproduce concurrency bugs.
\"I can think of only one concurrency bug that ever caused even theoretical data loss\" -- that's good. But beyond data loss, when a complex operation fails in the middle, it can be non-trivial to figure out which parts to redo.
