They also mention that “there are cases where browser APIs are backed by optimized native implementations that are difficult to compete with using Wasm … the team saw nearly a 100 times speedup of regular expression operations when switching from re2j to the RegExp browser API in Chrome” if so how they call RegExp from WasmGC or viceversa? 100 times speedup for native web apis is not something you can ignore, that’s the important lesson here, not everything compiled to wasm will result in a speed again
