As I understand, Folia can't help you if all your players are bunched together, but unlike having separate servers connected by Velocity or Bungee, it is a seamless experience -- everyone is in the same world and can visit anyone else without having to use commands, go through portals, or even wait for a loading screen. The "bubbles" that make up the world merge and split seamlessly, with special attention paid to avoid breaking vanilla game mechanics. [Speculation, I don't have the data and wasn't involved in the test] The test placed each 'team' 10240 blocks apart, which is close enough for a ~30 minute walk to get to another team (~4 minutes if you take the nether), so I assume a lot of bubble merging/splitting happened. It's also far enough away that, if the regionizing logic allows for it, you're split off onto another thread relatively early into your journey to visit another 'team' spawnpoint. This is a relatively realistic scenario for an SMP, where towns are usually 2,000 to 20,000 blocks apart.

Tbf “a ~30 minute walk to get to another team (~4 minutes if you take the nether)” doesnt seem very seamless to me. That’s quite a commute!

  Hah. On 2b2t, an "anarchy" server where any player can blow up any build and type whatever garbage into chat they want, players often opt to travel out tens of millions of blocks in an effort to make their builds extremely difficult to find. Can take many hours of nether travel to get to where you want to go. And inevitably, people still find them, usually through advanced techniques -- hacks that tell you whether a chunk is newly generated or part of an existing 'chunk trail' can be used to hunt down players that have taken great effort to hide their location. Anyways, a distance of 10240 is just how this particular test was set up. The regionizing is still useful in a much cozier world. As I understand the only way for it to be guaranteed that everyone is inside the same bubble (and therefore the ticking is all on a single thread) is for everyone to be in the same 768 block radius, or for there to be a line of players spaced this distance apart. It's rather atypical for a server to organically develop this way, since people really like to explore for hours before settling in the perfect spot. But some heavily planned/curated server are like this.
