In the graph above I've arranged the 28 Threadiverse instances with at least 200 monthly active users (MAU)—orange instances running Lemmy, green Piefed, and red Mbin—on the basis of which instances they defederate.

Each instance has its MAU count listed below, sourced from the latest MAU figures at Fediverse Observer, with adjustments made to the totals for Piefed (due to undercounting by outdated instances, as noted here; I used @Vicinus@piefed.zip's suggested estimate of 7,200 Piefed users) and Mbin (due to tardigram.com having a duplicate listing).

After adjustments, there are an estimated 43,287 monthly active Threadiverse users (35,184+7,200+903), of whom 87.84% are on the 28 largest instances. The percentages listed alongside the MAU figures correspond to each instance's share of the total MAU count.

Defederation data was sourced from Federation Checker. The tool doesn't support Mbin instances, so I left fedia.io in its own category. If any defederations are missing, feel free to let me know. Ideally such a chart should also include community blocks to better illustrate which instances block what, but that data doesn't appear to be as easily searchable.

I also noticed cases of some instances being listed as being defederated by another instance, despite not appearing on the defederation list for that instance (i.e. reddthat.com and lemmygrad.ml are listed as being mutually blocked, despite neither having the other on their block lists). In testing that federation, I noticed that !wholesome@reddthat.com did not federate to Lemmygrad while !memes@reddthat.com did, so clarification on that matter would be helpful.

While I'll update my generalized chart as needed to correct errors, perhaps at some point an automated federation mapping tool similar to the one feddit.de formerly hosted could be developed to more completely illustrate instance federation.

I think it’s for the best that Hexbear, Lemmygrad, and NSFW instances get defederated by as many instances as possible (users who want that specific content can sign up to those specific instances for it, while allowing the rest of the Threadiverse to more easily attract new users), but beyond that defederation should be reserved as a tool of last resort to avoid fracturing the Threadiverse further.

Yeah, I think a less culture-shocking introduction would help increase retention. The new W3C migration proposal, that was posted today, might help in reducing the sunk-cost in remaining with a specific instance, in the future.

Gladly; I’ll probably update the graph with a lower MAU threshold and any federation corrections that may be needed, and I’ll crosspost that too when it’s ready.

Looking forward to it :)

Note: looks like your downvote came from someone who posts to hexbear. I imagine they took issue with your want to migrate users/communities out of the ML instances. They weren't "serial" and only downvoted the one comment, so I don't think they're problematic.
