> Safari Technology Preview is ahead

My userbase isn’t using Safari Technology Preview, they’re using Safari

> the most anticipated web feature

I’m curious how you measured this - I have yet to be interested in :has(), but I am very interested in AV1 and PWA features...

Another point here: you can't update safari without updating ios itself. That means people who don't update or have old devices won't get new fetures. Also, safari STILL doesn't support a lot of new wasm extensions. So not really the picture GP is painting.

True. But each release of iOS gets to around 90% of the installed base by the time the next version of iOS gets rolled out; it’s non-issue for the vast majority of iOS users.

iOS 15 was updated 12 times [1] between September 2021 and July 2022; iOS users either got bug fixes or new features (usually both) in Safari each time, including users of the iPhone 6s, which shipped September 2015, more than 7 years ago.

Also, safari STILL doesn't support a lot of new wasm extensions.

According to caniuse [2], Safari’s WASM support seems to be just as current as Chrome and Firefox.

I don't think that tracks individual extensions. For example bulkMemory, simd, saturatedFloatToInt, and signExtensions are not implemented iirc.
