I don't think it has really descoped. They just want the transition to be smooth. So they start slowly. The lead japanese dev will most likely in 2026 go for more extension, and I also think this kind of has to be synced a bit with ractor (I think?).

Ractor is also strange. Do many people use ractors? I rarely see them used in actual ruby code out there. Right now it seems to me as if ractors are used by only ... say ... 1% or fewer of the ruby developers out there. A bit more than refinement users ... :P
