Apple's Safari investment is focused on features like tracking prevention and anti-fingerprinting. Stuff for users at the expense of developers.

I've seen what happens to web browsers that trail behind the industry in features.

It doesn't matter how nice the privacy features are, when a user encounters web site after web site that doesn't work right in their browser, they eventually each out to a more technical friend that recommends trying browser X. When browser X fixes their problems, they never return.

iPad / iPhone are captive rich markets, where only Safari is available. So companies/devs will keep on testing/supporting for it.
