There may be no feature complete alternatives, but there sure are a lot of email readers out there if you had to move off of it.
Addendum: The way I read that form, they will only consider whitelisting apps if the developers ask for it. As a user, I'm still screwed.
Even Windows Phone 8 has that confirmed: http://www.engadget.com/2013/03/15/google-caldav-support-sti...
In any case, if they're committed to preserving this feature then why are they implementing screening?
Seems unlikely they'll drop it given their approach to iOS so far has been to infiltrate the ecosystem with their own Google apps, though never say never I suppose.
As for why they're pushing people towards their own Calendar API, presumably so they can add/promote new features specific to Calendar which aren't present in CalDav. They can get more usage of Calendar-specific APIS/Features by pushing devs towards their own version, instead of letting them default to the CalDav API because that's what they're familiar with.
The responses gathered from API request form also act as a feedback mechanism for their own Calendar API, which they can use to fix any deficiencies.
Yes, and syncing Calendar data with Apple's calendar App is not this strategy.
Releasing a standalone "Calendar" app for iOS to keep it accessible, controlled, and branded on iOS devices after it stops working and Apple doesn't bother to request whitelisting but promotes iCloud instead, is.
Thanks for sharing. What a confusing mess!

Here's what you need to know:
Unfortunately, with Google changing the way it supports EAS,
your Google calendar can’t sync with the Calendar app.CalDAV is the standard and it's pretty clear that Google is backing away from that along with ActiveSync for enterprises and therefore silo-ing Calendar.
