If browser F is worse at battery life than browser S, people will figure that out and adapt for themselves. If it's a big difference, it's self-evident; and small differences should show up in the battery life tool and computer press.
Security-wise, the sandbox should limit damage to within the browser, and if it doesn't that's not the browser's fault. Maybe restrict access to password filling and such though / figure out how to offer an API to reduce the impact.
Standardization, eh? Forcing Safari on iOS and not making it available on the mass market platforms (Android and Windows) makes it a pretty wonky standard. I guess there's a claim to be made for the embedded browsing engine, but IMHO, that should be an app developer choice.
Safari exclusivity is the only reason we aren’t living in a 100% “this site built for chrome” world. I think folks must forget the IE days and how bad that was.
There is zero percent chance developers are wasting a second making sure their sites actually work cross platform if not for iOS (and iOS more moneyed user base).
Safari has long been better for battery than Chrome but people still install Chrome on their MacBooks.

No they won't. People on HN will. Not the average person.

The problem is, arbitrary code execution vastly expands the risks. Your "should" is doing all the work there.

Huh? Apple follows web standards. Why the heck should it make Safari available on Android and Windows? Safari isn't a standard, web standards are.

Unfortunately, the makers of a certain browser also control several major web properties, and regularly make 'mistakes' that break compatibility with competing browsers, while releasing a set of apps that 'forget' users' browser selections on a monthly basis.
Personally, I'd much prefer apple allowed a browser engine with proper ad blocking support. But I do worry that the moment they do so, the almost-monopoly browser market would become a total monopoly.
