[Question] Workflow - SML from PlantUML

[mkiepfer]

I have a general workflow question. I saw the possibility to generate a PlantUML from a given SML state machine (https://boost-ext.github.io/sml/examples.html#plant-uml-integration). But I am wondering if this isn't the vice-versa workflow.

Usually I design the state machine in a graphical UML diagram. This helps to keep overview, especially in more complex state machines. Based on this design that is design in any UML tool (e.g. Enterprise Architect), the state machine code is generated.
I don't see an out of the box solution to do this form Boost SML state machines.
Is there a reason for this?
Or did I overlook something?
Isn't that the reason the boost SML SDL is by design very similar to PlantUML?

The conversion from SML SDL to PlantUML may be good for documentation, but why not designing the SM in PlantUML and convert it to SML code.
