Because during development and test it is useful to tun just some of the 
steps without going through all the steps, which is very time consuming.
Since there is the --clear-autoresume option to explicitly clears the 
states, I assumed the default would be to not clear them.

Well, the patch was intended to better illustrate my question, not to 
apply it.

oh, ok. keepwork went completely unnoticed to me. I'm running catalyst 
v2 and from there I went into the repository to look at the code. Then I 
used the latest code on master branch to illustrate my question.
I'm pretty new to catalyst and I'm still figuring out the whole picture.

Thanks for the explanation.
