That seems totally reasonable but I wonder if there was some head butting in non-public channels given Bun is one of the biggest players in Zig and planned to push through a change like that on their own.

Even if there was anything in private channels, the reasons stated in that forum post are alone more than enough to reject Bun's Zig changes.

I wonder if they didn’t consider the problems of their changes in Zig what else do they not consider in Bun
