If such a path was set up, it would mean that M&TV would be added as an option for migration for questions on the main SFF site on the same level as the option for migration to SFF meta, and thus five users with 3k+ reputation would be enough to migrate a question from here to M&TV. Currently any migration except to SFF meta requires moderator intervention.
The highest-voted answer there says:
This discussion the other day shows that some people, including high-rep users, aren't entirely on the same page regarding what should be migrated. It's clear that non-SF&F movies or shows should go. It's pretty well established, I think, that asking about a non-genre show or movie is probably fine if the question related to a genre-ish element within that movie, but having a bit of genre-ish content doesn't make a show SF&F automatically. But what that discussion seem to indicate is that non-genre questions are off-topic, even if they're in an explicitly on-topic show.
This, I think, is unclear to all. Is this the consensus opinion? Where exactly is the line drawn about non-SF&F elements in SF&F works?
Once we've established that, I think the migration path should be added.
A year and a half have passed since then, and much has changed both in SFF and in M&TV, so I'm reopening this discussion. There are two issues to be established here:
Do we now have a clear policy on when migration to M&TV is appropriate?
If not, let's make one here!
If so, shall we set up a migration path?
(For what it's worth, M&TV had a similar discussion about migration to other sites, which is marked status-deferred, indicating that they won't be adding any migration paths in the near future, but may do so at some point.)
