In principle, if it does affect something, it seems likely there is already a buggy race condition. After all, if the timer and bottom half could trigger at the same time, which is the condition where the order is significant, then in principle the timer could have triggered slightly later because it depends on the host alarm behaviour.
No, the problem is when the timer function is _itself_ scheduling a bottom half. Before my patch there was a guarantee that the bh would run before TCG, now there is not. It can be fixed easily though.
