Basing a PR on a PR on a PR is not ok, please also wait for confirmation or rejection about whether we want to go ahead on this

Aside from the fact the core maintainers will never merge a PR increasing world size no matter how compatible or well done it is. How does the backwards compatibility affect performance of clients on this series of PR's on old servers/worlds for the 5.x.x series of minetest engine? If there is some terrible degredation in performance, then that should be fixed or discussed.
