Otherwise you end up with a Chrome situation where everyone just develops for a single browser.

You're commented needed to modified for current times. ;-)

Chrome is based on Webkit which is free and open source so that is a terrible analogy with IE that was proprietary.

Its being open source isn’t mutually exclusive with its not adhering to the standard

Chrome uses its own Blink and V8 now, and there are many cases where developers only design for Chrome and small differences in implementation can be a huge pain in Firefox/Safari.

Blink is also under a FOSS license so I am not sure what the problem is. Competiting browsers use Blink as well.

If it was that simple there would be no reason for Safari to lag behind.

No professional developer targets a browser when developing a web site unless its a captured audience with no choice. Professional developers follow the specification. Those who do otherwise are only mentioned in reddit headlines and other hobbyist sites.
