If I misunderstood, and this what OP meant, then I agree with your reasoning and solution.

I plan to map it with the in-between zone tagged with separate maxspeed:forward and maxspeed:backward tags.

Maybe it would be better to use the lower speed limit in the “no-man’s land”, since it would be unfortunate to be driving too fast while thinking one is folliwing speed limit. I assume it’s kind of ambigous what the allowed speed limit is?

For mapping, I agree with your logic. I just think we should err on the side of causion when things are ambigous.

Changing your username does nothing, because you have a unique, unchanging user ID. Just use something you don’s use anywhere else. Reputation is important in collaborative projects. You want to be known as a member that knows what they’re doing, and then you can be as anonymous as you like.
