The vendor, I'm sure, will have vanity items that aren't in normal gameplay.
So now we are differentiating what is normal gameplay and what isn't... My questions stands - if subscribers have unrestricted access to EVERYTHING what are the coins for? I bet my aunt's pants that the coins that go with the subscription will not be enough to buy everything (otherwise they would not award the bonus coins they are awarding because the normal points would be enough to cover everything). So your subscription will not cover EVERYTHING. And you are still paying the subscription.
They can't get their facts straight and do things right even in this "exciting" announcement.
