Do we feel okay with doing this deprecation without using the @deprecated function? @beeankha @kenodegard I feel we are ok as users have been warned for the last 6-7 years, but would be perfectly fine backtracking. The only internal use we have is for the tests. Everywhere else has been using the newer name.

@ryanskeith Let's go through the regular deprecation policy, the key is to follow the policy for risk of losing the overview of the special cases we've made along the way. A few more months for this won't be a problem compared to the years before ;)

[ryanskeith]

Will do.
