Occasionally, when major papers get written, they somehow end up leaked, such as when Google's (now published) Sycamore paper got temporarily posted on NASA's website.
While general questions may be OK, specific implementation questions, or questions that focus on such papers may be premature.
Should we take this approach? Or are our policies broad enough to address such questions anyway?
With two downvotes it seems the consensus is to not be inhibited from asking/answering!!
