Interesting read buddy. I also would like to understand what technical limitations did STINC encounter. Why did they decide that post can be published only within one community. So indeed, you're not the only one with this question in mind.
Cross-posting may look like a great idea on the paper, however I will discourage anyone to cross-post into community managed by me. It's just making things so spammy.
Solid read. Upvoted already,
