I trust CCEDK will polish their facilities to include more sophisticated systems as the FIMK transaction velocity on the exchange increases.
However it's true that similar looking deposit procedure without token was used by DGEX in its early days, and when NXT exploded in popularity it caused some trouble I remember. As long as the non-uniquely identified deposits are not disputed by a fraudster everything is good.
In any case, as always, do not store your cryptocurrency on an exchange. Transfer in, do your deed, and transfer out

I can only agree with you on all points, and FimK will be given the attention in full based on the feedback we receive in CCEDK, there is no doubt about it. Like every kind of business, success is built on mutual trust and the interest to develop together and according to demand, and it is the same here.
