Disagree. As someone who has tried to make web art that works cross-browser, I frequently follow standards and end up with something that works in Chrome, but breaks in Safari. I end up having to write hacks to detect Safari, cut out the parts of the standard they’ve implemented wrong, and find often crappy looking workarounds.

I’ve had issues with canvases just sort of “flashing” for no reason, and if you try to use SVG filters or other parts of the SVG standard that have been standardized for years... well Safari doesn’t choose to just ignore them. Instead it will sometimes just make the parts of the SVG affected by the filter turn black and then call it a day.

So I wouldn’t say that it’s as easy to create something that works fine in Safari and breaks in Chrome. Making something that works in Safari is just plain hard.
