Heh, this paragraph

    microsoft/git carries a similar patch (core.configWriteLockTimeoutMS,
    default off) for Scalar's tests. Defaulting to non-zero here because
    the worktree case fails silently.

in the proposed log message was enough to convince me that you'd be favor of it.

I think the "Waiting for response(s) to review comment(s)." is for

    So I'd rather lean towards dropping the cache and keeping the
    repository parameter.

that was expressed in a separate review in <agrIrGwSMFlKTx9x@pks.im> and haven't been responded to.

Thanks for pinging.
