I think cross-interpreter libraries can use OrederedDict correctly when they should use it. (They may run test on micropython, Jython and IronPython). The problem is that libraries which could otherwise be cross-VM compatible are not because they depend upon an implementation detail. So it becomes an additional porting burden on people trying to use the library on another VM that could've been avoided if we required people to be explicit about their needs. BUT... At this point I think coding up an example patch against beta1 offering a choice of disordered iteration capability that does not increase memory or iteration overhead in any significant way is needed. The problem is... I don't know how to express this as an API. Which sinks my whole though process and tables the idea.
"tables the idea" has the US meaning of close it down, not the UK meaning of open it up? :)
