I agree that immediately there might be confusion, but that's not really a reason not to change. The reason would be what is the benefit for change, and what is the cost of the confusion. I would argue in this case the cost is low.

The standard is long-standing and will only get stand for longer. So I don't see that as an argument against change. I would also argue that the tools are not going to get much better at reducing any confusion, so if you really believe that the tools are not good enough now, I don't think they ever will be.
