Is ZGC still in experimental?

I wanted to double check on this. Is the intention that ZGC in JDK 11 is not intended for production use and will never have backports to bring it up to a production ready level? Put another way - if we want to evaluate using ZGC for a production service, is it an effective pre-requisite to move to a later JDK than 11?
Obviously we can test with the JDK11 version, and if we don't happen to see any problems then can make an "at-your-own-risk" call on that. But the longer term plans for addressing issues will affect the appetite for whether to even start out on that version.

I would way that's unlikely at this time, given ZGC's experimental
status in 11.
