I'm not sure if we should specify a time within which we'll respond. I'd like to think that we respond much faster than two working days anyway, but I don't know if it's a good idea to promise this. Maybe 'as soon as we can' is good enough?

Also not sure if we need to say 'we might not merge immediately' - I think it's enough to say that we'll come back to you if we think changes are required before merging.
