I agree with the first part. If Mobile Safari had the reputation to be a security nightmare - with public attention rivaling the iOS6 Maps release, or IE in its worst days - then people would probably ask for a system-wide alternative. But I don't think that Apple ever considered to cause drama about the Google Maps release, just like they didn't cause a drama about YouTube, or Nokia Maps, or whatever. That seemed more like Google trying to take a cheap shot at Apple's approval process.
