Is this a true statement about a General Availability (GA) feature?

https://developer.okta.com/docs/reference/releases-at-okta/

A feature in General Availability (GA) is new or enhanced functionality that is enabled by default for all customers. Beginning in February 2017, features move from EA (enabled by request) to GA (enabled for all orgs) in a regular cadence:

EA features become GA in preview orgs in the first release of the month.

These same features become GA in production orgs in the first release of the next month.

Features in GA are supported by Okta Customer Support, and issues are addressed according to your Customer Agreement with Okta.

Documentation for features in GA release are not marked with any icons.
