Is the current recommended solution for this sort of thing.
Libraries look to be available for
GO
JAVA
JAVASCRIPT
.NET
NODE.JS
OBJ-C
PHP
PYTHON
RUBY
and you can roll your own using HTTP.
CardDAV is not well maintained, and even the contacts API using GData is superseded with the above.
With over 1 billion active users - my guess is engineering efforts are focused on serving that customer base, especially the growth in paying customers through google apps. Not sure where strict compliance with CardDAV would fall in the analysis.
A note that actually using some of these API's through their client libraries isn't totally the nightmare described - though my experience is very limited.
