Can you explain?

If you mean like api breakage, just don’t do that :)

We have sha logic comparison in there - it can tell which one is a parent of the other

If more than one available in the tree, it will pick the descendant

It seems to me it's not possible to have a spaces in a :main-opts entry (e.g :main-opts ["--space-separated-arg" "Joe Jack Williams Averell"]), is this is known issue?

Yes, use commas for now

Or in a case like this, not going to work for now

@alexmiller thanks, currently my workaround is simply to pass the args form the command line
