Hello, any comments, updates here ? Without support for these headers we really can't do SharedArrayBuffers and Atomics - which means no pthreads either. Mozilla has taken the lead on this and enabled it last year. Chrome is going to enforce it soon too - though they already allow SharedArrayBuffers on both Android and Desktop. Apple makes great CPUs (and devices) but you give up that advantage when you disable multithreading. Please support these headers so we can have supercharged multithreaded WASM powered webapps. Thank you.
