Yes, they should have stayed put, or slightly increased the limits. But they didn't act rationally and totally insecure, pushing this through just to prove a point.
ZKPs don't need that much data; fun fact, Citrea, cited as ine of the beneficiaries, rather uses Inscriptions instead of the op_return. Core burned all their social capital, and it was all for nothing.
At the same time, they are stalling what would be the right way to enable proper two-way pegs and thus scale bitcoin: CTV+CSFS.
It all makes no sense 🤷 (unless one subscribes to the theory this was a deliberate sabotage)
