I’m sorry, but that thread is a Grasshopper thread discussing the performance issues of scripts in GH. I have no idea how that discussion relates to using python in plain Rhino (outside grasshopper). Since I don’t use GH I would think raising issues not related to GH would be off-topic.
I would also like to see some answers to the issues being discussed in this thread .
What I would like to know :
Will IronPython continue to be supported?
Will the old Python editor be supported. Will bugs and regressions be fixed? Will new features be added?
You are implying both architectures offer benefits to users. That sounds to me like both should be given full support.
