To argue that having an Apple supported JVM was good, or that it doesn't matter because you'll just have a 3rd-party JVM instead, misses the fact that it's the change itself that will be cause the of problems. As crap as Apple's Java support has been, it was a known quantity: as a developer, you know what your Mac users have (currently it's "most have Java 6, but there are plenty of people still stuck with Java 5"). The same is true for Windows; even though the JVM comes from Sun, everyone gets that same JVM, and pretty much everyone has Java 6. It will take some time before a new one true JVM for Mac emerges. Furthermore, Apple's wishiwashiness on the support ("may not be included") will probably inhibit development on a true replacement.
