In the end, I'm still in favor of this change:
- I suspect the large majority of the use cases are for cartopy
- it's still possible to override the this default behavior by setting the ``projection`` kwarg yourself

If cartopy somehow changes its syntax (e.g. by renaming the transform kw) this code won't work.

cartopy uses ``transform`` because this is an interface provided by matlotlib: http://matplotlib.org/users/transforms_tutorial.html . This is not likely to change anytime soon.","{""total_count"": 1, ""+1"": 1, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,200593854

That is a corner case though.

Yes, I was about to ask @jhamman and @shoyer about their opinion about this. I'm actually not sure if this really is a corner case...","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,200593854

I think we need to document this somewhere, and also some tests would be nice.

Do you feel like trying to add the same functionality to normal 2d plots also? (this will represent a little more work so if you don't have time no big deal).
