Celluloid was an actor library which worked well with most ruby code. This is not the case for ractor. For starters, the ruby standard library is itself incompatible with ractor. Go ahead and try using logger inside one. Beyond that, a lot of mature libraries would have to be rewritten to fit ractors, and that's quite risky. Something as simple as a connection pool has to be done completely differently. That's a big red flag, considering that the value of ruby is its ecosystem. I actually tried making the libs I maintain ractor compatible. I recorded the constraints and suggested removing some of fhe annoying ones. Some got accepted, but it's not enough.
