Isn't every browser on iOS restricted to being a safari/webview shell?

OSS has always pushed back, just because of the maintenance burden in general, and corporate can just "fix it later" because there are literally devs on payroll. Or at least push through and then dump the project, the goal is just completely different, each style works in its context.

But I don't know if corporate software can really "push through" these new amounts of code, without also automating the testing part.

Yea that part is the icing on the cake.

I don't think the author's two samples look good.
