And even if they don’t give official notice, just ask which is why the support is there. If they give their stand before the fork, you can at least be a bit guaranteed something good if everything goes right. Like you said, so many exchangers did this in the past and it sure did make a lot of traders make quick decision on their forked chain.

Just make sure you are willing to give up the safety of your funds for the quick forked chain that you will be receiving though. So that implies more risk!
