A well-argued piece from @slightlyoff as to why we need to bring more capability to web, and why the privacy concerns brought up by Mozilla and Apple are kind of a red herring.
My brief time in W3C-land was filled with people yelling 'but fingerprinting!' any time someone proposed something useful. (Fingerprinting is the idea that the more features your browser exposes, the easier it is for a third party to track you as an individual collection of features.)
Apple's "structural under-investment" (as Alex puts it) in the browser is the main reason why iOS users on my instance have to resort to third-party apps to read posts on this server (no native notifications). This results in them having to use code that is authored by strangers instead of code that is maintained and run by me, their trusted admin. (Yes I suppose I could write an iOS app but it would take me a few years to learn to do that.)
This is a tiny, friendly fedi server!
