95%? I haven’t seen less than 20% mobile Safari on any site I’ve worked on in the last few years, and that’s not even including Edge / IE / Firefox and desktop Safari.

Our users are almost exclusively professionals working on Windows desktops. Probably a fairly unique situation but the point is standards are relative.

only true in american markets

I was actually talking about UK and Sweden (haven’t been to the US in 15 years).

what's the difference? these countries are basically american markets, everything west of belarus is kinda a software monoculture

I get to mandate the browser the work system supports (which is Chrome because that was what the majority of users used when I started so I went with what would cause the least amount of pain) but every feature I rollout works with Chrome, Firefox and mobile Safari (I test all three).

It adds very little extra work with the advantage of surfacing edge cases/issues that might have bitten me even if it was just Chrome in the mix.

Also from a business risk point of view tying the entire platform to a capricious vendor is dangerous and I've been around long enough to remember the days of IE5 then 6.

Once bitten, twice shy.

You would have loved IE6 back in the day.
